Why does my left hand go numb, tingling and cold?

The connection between the hand and the central nervous system is provided by the median, radial and ulnar nerves. Their damage or pinching causes unpleasant sensations: numbness, tingling, pain. Problems in the functioning of blood vessels are accompanied by the same symptoms, but a feeling of cold is added to them.

Numbness of the hands after sleep, which goes away after a short time, is a harmless phenomenon. This is often due to an uncomfortable sleeping position.

Due to pinched vessels, the limb is less well supplied with blood, loses sensitivity, and becomes cold. This problem can be easily solved - to restore blood flow, just rub your hand.

The wrist and fingers may become numb, tingly, or painful in response to constant stress. This pain is especially familiar to office workers and is caused by a pinched nerve. Regular pressure on it leads to the development of tunnel syndrome, which is fraught with complications.

And during the day it can be a signal of more serious diseases:

Compression form of osteochondrosis. A change in the condition of the intervertebral disc as a result of stress forms a hernia. The displaced cartilage tissue of the upper spine compresses the spinal roots, which disrupts the functioning of individual nerves. As a result, the hand hurts and goes numb.
Diabetic polyneuropathy, diabetes. Impaired insulin production leads to a sharp change in blood glucose levels and damage to blood vessels and nerve fibers. Along with the usual symptoms of diabetes, the patient feels a burning sensation in his fingers and numbness in his limbs.
Scleroderma. Due to hypothermia, frequent work with vibrating equipment, and infections of the nervous system, small vessels become inflamed. This leads to disruption of the production of connective tissue. Its excessive growth blocks the blood flow, which is why the fingers begin to go numb and change the color and thickness of the skin.
Angina pectoris, anemia, atherosclerosis. These diseases of the heart and circulatory system lead to insufficient blood supply to the limbs.
Pre-infarction state. Necrosis of the tissues of the heart, experiencing an acute lack of blood supply, is accompanied by severe pain in the sternum, left arm, under the shoulder blade for more than 20 minutes.
Stroke. Damage to the area of the brain responsible for the functioning of the limbs leads to impaired sensitivity, weakness, and even paralysis.

There may be other reasons: lack of B vitamins, alcohol abuse, sudden jumps in blood pressure.

What to do if your left arm is numb and doesn’t go away

If your hand or finger often, and even more so constantly, goes numb, then you should not put off visiting a doctor. Discomfort that occurs for minor reasons goes away quickly. Prolonged numbness or tingling of the left limb indicates the presence of serious problems in the body. Self-medication is unacceptable.

Of particular danger are stroke or heart attack, which can lead to death. An ambulance should be called at the slightest suspicion of an acute circulatory disorder. The sooner treatment begins, the greater the patient’s chances of surviving and continuing a full life.

Causes of numbness in the left shoulder

It happens that the feeling of numbness is concentrated only in the left shoulder area. There is the shoulder joint, which is subjected to many loads every day.

The most likely causes of discomfort are:

Tendinitis is an inflammation of the tendons that occurs as a result of long, active loads;
Bursitis - inflammation of the sacs with interarticular fluid;
Dislocation of the joint or displacement of the humerus.

Numbness is not always caused by injury or diseases of the cardiovascular and nervous system.

After severe illnesses, inflammation of the fibers of the joint capsule can occur, which leads to adhesive capsulitis or arthrosis of the shoulder joint. The pain syndrome is accompanied by limited mobility in the joint and impaired skin sensitivity.

Which doctor should I contact if a symptom appears?

If numbness in the hand occurs regularly or for a long time, the help of a specialist is required.

Doctors can help determine the cause of loss of sensitivity after examination:

Cardiologist;
Therapist;
Neurologist.

This is due to the possibility of numbness of the hand occurring due to the development of diseases in the area of their specialization.

If there is no specific suspicion of the cause of the symptom, you need to contact your local physician, who will prescribe general procedures. This is required to identify the area where the pathology occurs and refer you to the right specialist.

Pain in the heart area that accompanies numbness of the arm or part of it requires the attention of a cardiologist. Without additional symptoms, an initial consultation with both a local therapist and a neurologist is possible.

Based on the results of the examinations, it may be necessary to contact such doctors as:

Orthopedist;
Surgeon;
Rehabilitologist;
Osteopath.

Diagnosis of the disease

Treatment for stiffness of the limbs is aimed at eliminating the cause that caused this condition. A disease is detected, one of the symptoms of which is partial or complete loss of sensitivity in one or two hands at once. This requires a range of research methods.

In order to diagnose the cause of the symptom of hand numbness, after an initial medical examination, a series of examinations may be prescribed.

Among them are laboratory tests:

General blood analysis;
Blood test for hormones;
Vitamin analysis.

Upon receiving the results of laboratory tests, the doctor draws up a general preliminary picture of the state of health.

To do this, he systematizes and analyzes information:

Obtained data from laboratory tests;
Results of external examination of the patient;
Symptoms of numbness based on the patient’s complaints. Comparison of additional signs accompanying numbness.

Based on the generalized information, an examination is prescribed. This is required to confirm or refute suspicions of the presence of specific disorders in the activity of a particular area of the body.

The main task of the doctor is to determine the cause of the loss of sensitivity in the hand. The collected material is examined to exclude simple mechanical compression of blood vessels, household and industrial factors not related to diseases.

Woodiness can be a harmless temporary manifestation of a separate physical impact, but it can also be a factor indicating the development of serious pathologies and disturbances in the normal functioning of internal organs.

Myocardial ischemia, stroke, diabetes mellitus, problems in the spine and a number of other diseases can be hidden under such a symptom as numbness in the arm. Often numbness occurs as a result of the progression of osteochondrosis.

To identify the disease itself and the extent of damage to the body, the patient is sent for specific examinations.

Frequently prescribed examinations:

Radiography. Detects damage to the spine, the presence of hernias, displacements of intervertebral discs, the appearance of neoplasms, curvature, the development of degenerative pathologies, and infectious diseases.
Magnetic resonance imaging. Prescribed for suspected radicular syndrome - compression of the spinal nerves.
Ultrasound duplex scanning. Allows you to determine the patency of veins and arteries, the presence of blood clots in them. Examines the walls of blood vessels, detects abnormal changes, evidence of blockage, and the presence of plaques.
EEG. It is carried out when there is a suspicion of disturbances in the functioning of the central nervous system.
CT scan.
Electroneurography. A study of the nervous system allows you to assess the extent of nerve damage.
Electromyography. The method consists of recording electrical muscle activity, which makes it possible to determine the speed of nerve impulses transmitted. It is used to assess human motor dysfunction in orthopedics.
UZDS. Shows blood flow in the area being examined.

The examinations can be prescribed separately or in combination with each other to create a more complete picture of the health status of the body and its individual organs.

Preventive methods

Numbness of the limbs causes discomfort and hinders movement. It is possible to reduce the severity of symptoms, and sometimes eliminate them completely, through systematically implemented preventive measures.

The most effective measures include:

Moderate physical activity. Represents the daily implementation of a set of specially designed health-improving exercises. This allows you to constantly keep your arm muscles in good shape and strengthen their resistance to numbness. Physical activity is important for diseases of blood vessels and joints.
Proper nutrition, excluding fatty and spicy foods from the diet. Inclusion of fruits, herbs, vegetables, fish, vegetable oils
Reduce salt intake.
Stop drinking alcohol and nicotine.
Protection from the cold. Freezing your hands has a negative effect on the condition of your joints. Treat them with care - keep them warm, wear clothes mainly made from natural fabrics. In cold weather, wear gloves and mittens.
A small physical warm-up for the arms, alternating with a load on the hands and palms. Circular rotations of the hands have a beneficial effect on relieving muscle tension during work involving heavy loads on the upper limbs and spine. When working with your hands for a long time, take a break every 45 minutes for a massage. This will restore blood circulation and prevent blood stagnation.

Hand exercises

To reduce the severity of symptoms of numbness in the upper extremities and prevent the frequency of manifestations of the uncomfortable condition, it is recommended to improve blood circulation in the hands with therapeutic exercises.

The set of developed exercises can be common for all areas of the arm that are susceptible to numbness, or changed separately for each of them.

Numbness due to carpal tunnel syndrome is common. It accounts for more than 60% of all cases. It is characterized by loss of mobility in the fingers and hands up to the wrist. Less often - up to the elbow or shoulder. Gymnastic exercises for illness give the greatest therapeutic results.

Damage to the spine, the formation of intervertebral hernias, and displacement of joints cause numbness in the hand in 30% of cases. All other diseases lead to a loss of hand sensitivity of 10%.

Gymnastics are carried out to reduce symptoms. The symptom can be completely eliminated only after treatment of the underlying disease.

Exercises for hands and fingers:

The palms folded together are placed in a vertical position in front of the chest. Rubbing movements are carried out with the palms for 2 minutes.
The fingertips of both hands touch each other, and they make short pressing movements for several minutes.
Fingers or other problem areas of the upper extremities are massaged. Rubbing massaging movements are carried out in a clockwise direction. Attention, when concentrating the loss of sensitivity in the area of the hand, is given to the tips of the index fingers. The massage is carried out alternately, first for one, then for the other hand.
Vigorously clench and unclench your hands for a few seconds. Alternates with light finger massaging.
Squeezing a tennis ball with your palms.

Exercises for the shoulder and forearm area, elbow area:

Massage with short pressure on a point on the forearm. Performed 20 times for each shoulder. The point is found by measuring a distance of 3 fingers from the bend line of the elbow towards the hand.
Raising and lowering the arm with a delay of several seconds in each position. Performed alternately 10-15 times for each limb.
Adopting a lying position. Raising your hands, clenching your palms into fists and unclenching them several times. Lowering your arms, stretching them along your body, relaxing your muscles. The exercise is repeated 8-10 times.

Exercises are carried out when a symptom of numbness appears. For prevention, they are performed systematically, depending on the frequency of hand numbness - 3 or 4 times a week. In case of frequent loss of hand control - daily.

Traditional methods of treatment

Remedies used in traditional medicine are recommended for use only in combination with the main treatment. A preliminary consultation with a doctor about the possibility of side effects as a result of taking the medication is required.

Alternative medicine methods used to eliminate the symptoms of numbness of the upper extremities:

Taking a bath with rosemary before bed. An infusion prepared within half an hour from 3 liters of water and a handful of flowers is added to a bath filled with water. Take a bath for a quarter of an hour.
Rubbing numb areas of the hand with a product prepared from camphor (10 ml) and ammonia (50 ml) alcohols. The resulting mixture is diluted with one liter of water at room temperature. One spoon of table salt is added to the finished product.
Numbness of the elbow is treated with boiled wheat porridge, folded into a fabric bag. To obtain relief that occurs immediately, the bag is applied to the elbow and held for half an hour.
Garlic cloves cut into slices are infused in vodka for 2 weeks. Take orally 2 times a day before meals, 5 drops of the product diluted in one teaspoon of water. The duration of the course of treatment is one and a half months.
Tying the wrist with woolen thread.
Powdered round black pepper is poured with vegetable oil and left for half an hour with occasional stirring. The resulting product is rubbed warm into problem areas 2 times a day.

Consequences of untimely treatment or lack thereof

Numbness, accompanied by additional symptoms and painful sensations in different areas of the body, is an alarming sign of possible ongoing pathologies of internal organs. Asymptomatic numbness in areas of the upper extremities, systematically recurring or long-lasting, does not happen just like that.

This condition should not be ignored. The disease, the symptom of which is stiffness of the hand, continues to develop and will not go away on its own without proper treatment.

Depending on the cause of hand numbness, the consequences of delaying seeking medical help will be severe and sometimes irreparable. Negligent attitude towards one's health leads to serious complications of diseases or even death.

If there is a temporary loss of sensitivity in the tips of the fingers, which occurs due to diseases of the spine, failure to consult a doctor leads to the following consequences:

Deformations in its departments;
Compression of nerve endings;
The rapid development of illness and disability.

For the main cause of numbness associated with carpal tunnel syndrome, untimely treatment leads to the following consequences:

Swelling of the wrist tendons;
Pinched median nerve;
Burning sensation in fingers;
Complete loss of mobility of the thumb, atrophy of its muscles;

Thrombosis, leading to numbness of the fingers, manifests itself in an already developed stage.

The progression of the disease occurs rapidly and, if left untreated, leads to a number of dangerous complications:

Spread of numbness, starting from the fingers and gradually affecting the entire hand;
Necrosis of muscle tissue;
Separation of a blood clot, and, as a result, death.

Vascular, rheumatic diseases, Raynaud's syndrome, which are accompanied by stiffness of the hand, in their severe form lead to dangerous conditions:

Additional pain support;
Blue fingers;
Severe swelling;
Gangrene.

Gradually, numbness of the entire arm or part of it without timely diagnosis of its cause and treatment corresponding to the diagnosis leads to complications. The limbs may lose sensitivity, the ability to gesture, feel touch, and hold objects in their hands.

Hello dear readers. Numbness of the left hand is a symptom that indicates abnormalities in the functioning of our body. Moreover, it can indicate both completely harmless problems and a rapidly developing heart attack or stroke. Most often, discomfort is caused by dysfunction of the circulatory or nervous systems. But one should not exclude trauma or a person’s psychosomatic state as a source of numbness. To understand the source of limb numbness, you should understand the nature of the sensations, pay attention to habits, a number of chronic and acquired diseases, and only then can you make assumptions. Today we will look at why the left hand goes numb, as well as the measures that should be taken.

Nature of pain

Always, first of all, pay attention to the nature of the unpleasant sensations. It is they who will tell you, and the attending physician, a number of reasons that could provoke numbness.

For example, short-term numbness of one or more fingers, which does not have pronounced regularity, can be associated with completely harmless reasons.

Among them are muscle compression or prolonged immobility of the limb. Both problems can be solved with light massage and restoration of limb activity.

Short-term but frequent attacks of numbness, as well as constant slight discomfort, are a dangerous symptom.

In this case, the presence of damage to the central nervous system or serious circulatory disorders associated with heart disease cannot be ruled out. This type of pain is often a symptom of the development or exacerbation of chronic diseases.

Complete loss of sensation in the left hand or its parts is a reason to immediately call an ambulance or visit a doctor.

In such cases, the development of a stroke, heart attack or previous conditions cannot be ruled out. In addition, complete numbness of the limb may occur due to injury.

My left hand is going numb - what are the reasons and what to do?

It will allow you to suspect the presence of a serious illness, and will also speed up the diagnosis in case of hospitalization.

We divided all existing causes that directly or indirectly cause numbness in the left hand into three groups.

The first is household, associated with daily human activity, they are the safest and rarely entail serious consequences.

The second is medical, they have serious help in the form of qualitative changes in the basic functions of the body.

The latter - injuries are associated with the main injuries that a person can receive.

1. Household

Numbness is not always caused by illness. For example, it may be caused by insufficient blood supply to nerve bundles or muscles.

This happens in the following cases:

— Paresthesia caused by excess pressure on muscle tissue - clothing, backpack or other heavy load.

— Poor sleeping position . A similar situation, only pressure has a longer lasting effect and, as a result, sensitivity decreases, up to complete numbness of the limb.

In this case, not only muscle tissue, but also a number of other tissues suffer due to deterioration of the blood supply to the arm.

— Occupational “disease” . Pianists, needlewomen, programmers and a number of other professions associated with overstrain of muscles and tendons can cause discomfort in the left hand. In this case, the problem can affect both hands.

— Holding your hand above your head . In this position, the human heart is not able to provide adequate blood circulation, therefore, due to its disruption, loss of sensitivity begins.

2. Medical

Alas, excluding platitudes, the causes of numbness remain medical, the source of which is illness or qualitative changes in the normal state of the body, plus injuries.

Let's look at what are the most common and serious pathologies that cause paresthesia?

3. Vitamin deficiency

Such a banal but dangerous problem as vitamin deficiency leads to damage to the nerve membranes due to their insufficient nutrition.

The result is a decrease in sensitivity of the limbs. A special feature of this problem is the fact that along with the left hand, discomfort can also occur in other parts of the body.

How to determine it:

Decreased immunity.
Disturbances in the normal functioning of the gastrointestinal tract.
Hair fragility, dandruff, dry skin.

4. Atherosclerosis

The essence of this disease is that normal blood circulation stops due to cholesterol plaques.

Blockage of blood vessels inevitably leads to various consequences. If the problem is localized in the brachial or ulnar artery, then as a result the arm begins to go numb.

In addition, the limb loses its normal color, performance decreases, and tissue degeneration occurs over time.

How to determine? Most often, the disease worries people over 40 years of age. Numbness is accompanied by goosebumps, and the fingers begin to “get cold.”

5. Osteochondrosis

The disease manifests itself as the inevitable destruction of vertebrae, joints, and ligaments. In an advanced state of the disease, destruction affects the nerve channels, completely or partially blocking their functionality.

Depending on the affected cervical region, numbness or complete failure of individual parts of the body can be observed. The lower cervical region is responsible for the left arm.

How to determine?

Osteochondrosis has a number of auxiliary symptoms that greatly simplify the diagnosis:

Numbness starts from the thumb.
Tingling sensations appear, which intensify with movement.
Headaches accompanied by dizziness.
Blurred vision when bending over or standing up suddenly.
High blood pressure.

6. Herniated intervertebral discs

Like osteochondrosis, this cause is caused by an effect on the nerve canals. The main difference is that the pressure on the nerve is exerted by the hernia.

In addition to discomfort in the left arm, the patient experiences severe back pain, including loss of motor functions.

The solution to the problem is most often represented by surgical intervention.

7. Carpal tunnel syndrome

An ailment of office workers that appears as a result of working on a keyboard and awkward hand position.

Increased stress on the carpal tendon, immobility of the limb, and a number of other aspects of office work lead to swelling of the median nerve and swelling of the tendon.

Symptoms:

Selective numbness of fingers.
Tingling limbs.
Swollen wrist.

8. Pre-infarction state

One of the most dangerous causes of numbness in the left hand. It begins with loss of sensation in the ring and little fingers.

In this case, the heart has attacks, and the medications do not have the desired effect, and pain appears, radiating to the arm.

Against the background of the described symptoms, anxiety and panic develop, the patient is bothered by dizziness and cold sweats.

If you notice such symptoms, you should seek medical help as soon as possible.

With prompt treatment, there is a chance to prevent an attack and preserve the health and functional abilities of the patient’s body.

9. Raynaud's disease

A special type of illness associated with disruption of the small vessels responsible for the blood supply to the hands.

The disease occurs in attacks, during which the blood vessels contract, preventing normal blood supply to the hands.

In this case, one can observe both a symmetrical and localized effect (the right or left hand goes numb).

10. Diabetic neuropathy

In this case, damage to the nerve endings occurs in diabetic patients. At the same time, the process of nerve dystrophy is final and if numbness has appeared, it will be impossible to restore the functionality of the organ completely.

The solution is strict control of sugar levels. At the moment, there are no other ways to prevent loss of sensitivity, due to a lack of understanding of how the disease works. To date, the exact reasons for the death of nerve endings have not been established.

11. Chronic kidney disease

As a chronic illness worsens, nitrogen compounds accumulate in the blood. They and a number of other toxic substances in the blood begin to affect the central nervous system, gradually reducing the sensitivity of the nerves.

Most often, the problem affects large areas of the body, although it can also be localized in individual limbs.

12. Injuries

Finally, numbness in the left hand can result from any injury - bruise, sprain or fracture. However, the injury does not always affect the hand itself.

The left arm is directly and indirectly affected by injuries to the neck, spine, and shoulder joint. On the positive side, injuries are easier to identify, since numbness occurs almost instantly after injury.

On the other hand, some injuries have serious traumatic consequences, for example, a spinal injury can lead to complete failure of the nerve endings of the left arm.

Nerves can also be damaged as a result of arm fractures, when a sharp edge of the bone damages a bundle of nerves.

Other symptoms:

Numbness of the hand when stationary.
Sharp pain when trying to move your fingers or limb.
Blueness of the skin.
Swelling at the site of impact.
Complete numbness of the hand.

When visiting a doctor, be sure to mention even minor blows or other injuries that preceded the numbness of the hand.

What to do if there is numbness in a limb? When to see a doctor?

Having studied possible problems and their danger, everyone should understand that there are cases when immediate contact with a doctor can save the patient’s life.

On the other hand, slight discomfort may be caused by overwork or incorrect position of the limb.

That is why pay attention to the nature and duration of pain.

A single and short-term incident of numbness requires only a little attention. If you are concerned about frequent pain, consult a neurologist for advice.

Finally, sudden and complete numbness in the hand is a sure sign of a serious problem with the nervous system or heart. In such cases, go to the nearest emergency room or call a doctor.

How to treat?

There are a lot of possible treatment options, as well as the causes of the problem. Therefore, before taking measures to prevent or treat numbness in the left hand, consult a neurologist.

His professional consultation will help you choose the right and effective course of treatment.

If there are no obvious reasons for hospitalization, then it is necessary to conduct an examination, which includes:

- History.

— Inspection.

— Blood and urine tests.

— X-ray.

A number of other, narrow studies.

The doctor will determine the exact number of tests, and based on them, he will establish a diagnosis and find out why the left arm is numb. Next, the patient will receive recommendations on further actions and, if necessary, a course of treatment.

Most often, treatment consists of a number of medications (anti-inflammatory, immunostimulating, restorative, etc.), which are prescribed based on the results of the examination.

As an additional measure and to prevent complications, physiotherapeutic procedures are prescribed.

An important rule for effective treatment is compliance with the doctor’s recommendations regarding the load on the limb. By avoiding overload, hypothermia and intoxication of the body, you can significantly speed up treatment.

If the described conservative measures do not bring the desired result, then surgical intervention may be prescribed. In some cases, surgery is the only chance to restore sensitivity and functionality of the limb.

Important! Don't self-medicate! Otherwise, you risk the functionality of the limb.

Numbness in the left arm may be caused by a problem with the nerves, circulation, muscle tissue, or ligaments.

Based on this, as well as other information presented above, anyone can suspect one or another cause of discomfort.

The main thing to remember is that doctors make a diagnosis and prescribe treatment; our task is to respond to the body’s signals in a timely manner and prevent possible complications.

You change your position, do a couple of movements (“get the blood flowing”) - everything goes away. To prevent this from happening again, analyze your lifestyle.

Prolonged paresthesia, accompanied by pain, spreading to other parts of the body, should be alarming. Moreover, the sensations cannot be associated with injuries, work, sports or uncomfortable posture. It's all about a serious illness. Let's take a closer look at why the left hand goes numb.

Household reasons

Numbness in the left hand is not always associated with illness. Discomfort is explained by impaired blood supply to nerve fibers and muscle tissue. Why is this happening:

The muscles are compressed by uncomfortable and tight clothing, a heavy bag, backpack, etc. Even a tight tonometer cuff (when measuring blood pressure) can provoke short-term paresthesia.

Bad pose. If your left hand goes numb in the morning, it means there was a lot of pressure on it at night. The habit of sleeping on your stomach, placing a limb under you, leads to a decrease in sensitivity. When a girl sleeps on her shoulder, blood circulation also suffers.

If you sit for a long time with your arm over the back of the chair, the blood vessels and nerve endings are compressed. Blood supply is disrupted. At the same time, the limb becomes cold and “goosebumps” appear.

Excessive activity of muscles and tendons. For needlewomen, pianists, and people who work a lot on the computer, the hand is under constant tension. This is why numbness occurs in the fingers on the left hand (if the main load falls on this side).

Long training, hard physical labor. During intensive training, the heart cannot cope with the blood supply to the muscles of the limb. The left arm is taken away when it is raised above the heart line for a long time.

Constriction of blood vessels in cold weather. Paresthesia is experienced by people who have congenital narrowing of the ulnar or brachial arteries.

A frequent companion to a sedentary lifestyle is insufficient blood supply to all organs and tissues. Hence the periodic numbness of the limbs. More movement means better blood supply to the vessels.

Medical

Loss of sensation in the hand, forearm, or entire limb may indicate serious pathologies of the blood vessels, spinal cord, heart and other internal organs. It is necessary to look for specific causes of numbness with a doctor. The specialist studies the clinic in detail, prescribes examinations - makes the correct diagnosis and determines treatment.

The information provided below is for informational purposes only.

Avitaminosis

Numbness is caused by a deficiency of vitamins A and B. Due to the lack of these substances, metabolism is disrupted, as a result of which the nerve sheath is damaged. Loss of sensation leads to paresthesia.

immunity decreases - the body is highly susceptible to infections and viruses;
the condition of the skin and hair worsens (dry skin, dandruff appears);
There are problems in the functioning of the gastrointestinal tract.

review your diet;
give up bad habits (under the influence of alcohol, many vitamins are simply not absorbed);
take multivitamins.

Atherosclerosis

Cholesterol plaques clog blood vessels throughout the body. With severe atherosclerosis, approximately 60% of the vascular bed is damaged. Blood movement becomes difficult.

The pathological process can be clearly expressed in certain parts of the body. If it is the ulnar or brachial artery on the left, then the arm goes numb. Atherosclerosis develops after 40 years.

chilliness and coldness of the fingers;
"goosebumps";
pallor of the skin.

medications prescribed by a doctor (modern drugs cope quite successfully with atherosclerosis);

surgical methods (in case of serious blockage, surgical intervention is prescribed - bypass surgery, vessel replacement, etc.).

Osteochondrosis

Degenerative destruction of vertebrae, joints, ligaments, intervertebral discs. When dystrophy worsens, pathological mobility of the spine develops - nerve fibers and blood vessels are pinched. Paresthesia is caused by pathology of the lower cervical zone.

the thumb on the left hand, index and ring fingers (less commonly, the little finger and middle finger) go numb;
“goosebumps” and tingling sensations appear (the sensations intensify with a sharp turn of the neck or tilt);
headache and dizziness;
periodically the vision becomes dark and the blood pressure rises greatly;
with osteochondrosis of the thoracic region - girdle pain in the sternum.

Treatment methods for osteochondrosis:

taking non-steroidal anti-inflammatory drugs;
manual therapy;
massage;
physiotherapy.

Carpal tunnel syndrome

The disease affects operators, office workers, needlewomen, painters and other manual workers. Due to the high load on the carpal tendon, the median nerve swells.

numbness of the fingertips, loss of sensitivity in the hand (on the left hand, if it is the working one);
tingling, “goosebumps” at night;
pain and burning in fingers;
cramps, swelling of the wrist;
decreased activity of the thumb.

at initial symptoms, try to reduce the load on the working arm;
Periodically rest your hand and do simple exercises;
if the clinic does not back down, consult a doctor immediately (you can lose your working arm with such a diagnosis).

Pre-infarction state

Far advanced stage of progressive angina. Occurs due to stress, insufficient treatment, smoking, fatty diet, age, etc. The release of blood into the peripheral vessels decreases - first, paresthesia of the ring finger is felt, then the little finger of the left hand goes numb.

Other signs of an impending myocardial infarction:

the heart hurts paroxysmally, medications do not help;
pain radiates under the tongue, under the collarbone, into the arms;
cold sweat, anxiety, fear of death appears;
atypical picture – weakness, dizziness, insomnia.

Such a clinical picture requires urgent consultation with a doctor. In a hospital setting, the attack is stopped and long-term treatment is prescribed.

Stroke

When an artery is blocked by a blood clot or a large vessel ruptures, a stroke develops. With pathology, the little and ring fingers on one hand, the muscles of the face, and legs (also on one side) often lose sensitivity.

severe weakness;
difficulty speaking, breathing, coordination;
unexpected visual impairment;
dizziness;
high pressure.

If such symptoms occur, you should urgently call an ambulance. Delayed treatment is fraught with persistent functional disorders. Already when one little finger on the left hand goes numb, you need to worry.

Injuries

Hand injury and traumatic brain injury sometimes lead to paresthesia. My hand goes numb and hurts. Other unpleasant symptoms appear:

With head injuries, the patient feels weak and nauseous. Hands may also become numb due to neck injuries.

Why do the fingers on the left hand go numb after an injury:

due to plaster, muscle atrophy occurs;
in immobilized muscle fibers, blood circulation is impaired;
numbness occurs.

After injuries or surgeries, hands need to be developed. For recovery, the doctor prescribes physiotherapeutic procedures, massage, and acupuncture.

There are many reasons for numbness in the left hand. If the unpleasant sensation bothers you constantly, pain appears, you should immediately see a doctor.

Let's look at what are the most common and serious pathologies that cause paresthesia?

3. Vitamin deficiency

Such a banal but dangerous problem as vitamin deficiency leads to damage to the nerve membranes due to their insufficient nutrition.

The result is a decrease in sensitivity of the limbs. A special feature of this problem is the fact that along with the left hand, discomfort can also occur in other parts of the body.

How to determine it:

Decreased immunity.
Disturbances in the normal functioning of the gastrointestinal tract.
Hair fragility, dandruff, dry skin.

4. Atherosclerosis

The essence of this disease is that normal blood circulation stops due to cholesterol plaques.

Blockage of blood vessels inevitably leads to various consequences. If the problem is localized in the brachial or ulnar artery, then as a result the arm begins to go numb.

In addition, the limb loses its normal color, performance decreases, and tissue degeneration occurs over time.

How to determine? Most often, the disease worries people over 40 years of age. Numbness is accompanied by goosebumps, and the fingers begin to “get cold.”

5. Osteochondrosis

Depending on the affected cervical region, numbness or complete failure of individual parts of the body can be observed. The lower cervical region is responsible for the left arm.

Osteochondrosis has a number of auxiliary symptoms that greatly simplify the diagnosis:

Numbness starts from the thumb.
Tingling sensations appear, which intensify with movement.
Headaches accompanied by dizziness.
Blurred vision when bending over or standing up suddenly.
High blood pressure.

6. Herniated intervertebral discs

Like osteochondrosis, this cause is caused by an effect on the nerve canals. The main difference is that the pressure on the nerve is exerted by the hernia.

In addition to discomfort in the left arm, the patient experiences severe back pain, including loss of motor functions.

The solution to the problem is most often represented by surgical intervention.

7. Carpal tunnel syndrome

An ailment of office workers that appears as a result of working on a keyboard and awkward hand position.

Increased stress on the carpal tendon, immobility of the limb, and a number of other aspects of office work lead to swelling of the median nerve and swelling of the tendon.

Selective numbness of fingers.
Tingling limbs.
Swollen wrist.

8. Pre-infarction state

One of the most dangerous causes of numbness in the left hand. It begins with loss of sensation in the ring and little fingers.

In this case, the heart has attacks, and the medications do not have the desired effect, and pain appears, radiating to the arm.

Against the background of the described symptoms, anxiety and panic develop, the patient is bothered by dizziness and cold sweats.

If you notice such symptoms, you should seek medical help as soon as possible.

With prompt treatment, there is a chance to prevent an attack and preserve the health and functional abilities of the patient’s body.

9. Raynaud's disease

A special type of illness associated with disruption of the small vessels responsible for the blood supply to the hands.

The disease occurs in attacks, during which the blood vessels contract, preventing normal blood supply to the hands.

In this case, one can observe both a symmetrical and localized effect (the right or left hand goes numb).

10. Diabetic neuropathy

In this case, damage to the nerve endings occurs in diabetic patients. At the same time, the process of nerve dystrophy is final and if numbness appears, it will be impossible to restore the functionality of the organ completely.

11. Chronic kidney disease

Most often, the problem affects large areas of the body, although it can also be localized in individual limbs.

12. Injuries

Finally, numbness in the left hand can result from any injury - bruise, sprain or fracture. However, the injury does not always affect the hand itself.

On the other hand, some injuries have serious traumatic consequences, for example, a spinal injury can lead to complete failure of the nerve endings of the left arm.

Nerves can also be damaged as a result of arm fractures, when a sharp edge of the bone damages a bundle of nerves.

Numbness of the hand when stationary.
Sharp pain when trying to move your fingers or limb.
Blueness of the skin.
Swelling at the site of impact.
Complete numbness of the hand.

When visiting a doctor, be sure to mention even minor blows or other injuries that preceded the numbness of the hand.

What to do if there is numbness in a limb? When to see a doctor?

Having studied possible problems and their danger, everyone should understand that there are cases when immediate contact with a doctor can save the patient’s life.

On the other hand, slight discomfort may be caused by overwork or incorrect position of the limb.

That is why pay attention to the nature and duration of pain.

A single and short-term incident of numbness requires only a little attention. If you are concerned about frequent pain, consult a neurologist for advice.

Finally, sudden and complete numbness in the hand is a sure sign of a serious problem with the nervous system or heart. In such cases, go to the nearest emergency room or call a doctor.

How to treat?

There are a lot of possible treatment options, as well as the causes of the problem. Therefore, before taking measures to prevent or treat numbness in the left hand, consult a neurologist.

His professional consultation will help you choose the right and effective course of treatment.

If there are no obvious reasons for hospitalization, then it is necessary to conduct an examination, which includes:

Blood and urine tests.

A number of other, narrow studies.

Most often, treatment consists of a number of medications (anti-inflammatory, immunostimulating, restorative, etc.), which are prescribed based on the results of the examination.

As an additional measure and to prevent complications, physiotherapeutic procedures are prescribed.

Important! Don't self-medicate! Otherwise, you risk the functionality of the limb.

Numbness in the left arm may be caused by a problem with the nerves, circulation, muscle tissue, or ligaments.

Based on this, as well as other information presented above, anyone can suspect one or another cause of discomfort.

The main thing to remember is that doctors make a diagnosis and prescribe treatment; our task is to respond to the body’s signals in a timely manner and prevent possible complications.

Left hand goes numb: reasons

Numbness of the left hand

The human body is an integral system that has a complex structure, is constantly in close connection with the external environment, and is capable of acutely reacting to any changes, causing a number of ailments and symptoms that affect a person’s quality of life. One of the few, but at the same time common signs is numbness of the limbs. In the medical practice of doctors, we often encounter patients who complain that their left arm is numb. This condition is quite unpleasant, and can also be a harbinger of complex diseases. Why the left hand goes numb - the reasons are quite diverse, but in any case, such an ailment should not be left without due attention, especially in cases where it occurs frequently. Let's try to understand and consider the main reasons why the left hand goes numb, the diseases for which this symptom is characteristic, and also what to do when numbness in the upper extremities bothers you!

Why does my left hand go numb?

Numbness of the left hand is a rather unpleasant condition, which is often accompanied by a tingling, “crawling” sensation. Basically, the cause of numbness in the arm from the shoulder to the fingers can be hidden in both serious illnesses and everyday problems, with prolonged and incorrect body position. In medicine, numbness of the upper or lower extremities can be found under the term “paresthesia,” which is characterized by impaired skin sensitivity as a result of compression or irritation of nerve endings. In addition to numbness, a person often feels a decrease in pain sensitivity, tingling, the hand may become bluish, coldness is felt, and sometimes pain.

Compression of nerve endings is the cause of numbness in the left hand

Symptoms of hand numbness depend on the very reason that provoked this condition. It is important to note that the left hand can go numb not only in people with a history of some kind of disease, but also in those who lead a sedentary lifestyle, spend a lot of time at the computer, or when the body is in an uncomfortable position for a long time. position It’s not uncommon for many of us to notice that our hands go numb in the middle of the night or in the morning after sleep. In such cases, most likely the body was in the same position during sleep. The cause of this phenomenon is considered to be poor circulation and muscle strain, which is not associated with any pathology.

Numbness of the left arm can appear against the background of vascular disorders, when there is compression of the arterial blood supply, which is considered a source of oxygen and other nutrients for the full functioning of the body. In cases where the arterial blood supply is impaired, the internal organs, and in particular the heart, do not receive enough oxygen, which leads to a feeling of numbness and pain in the left arm. This condition can lead to the development of such serious diseases as myocardial infarction or stroke.

Vascular disorders - cause numbness in the left arm

Often the left arm may go numb due to disorders in the spine, when degenerative processes occur with the subsequent development of pathologies.

Causes of numbness in the left hand

As noted above, numbness of the left hand can appear not only against the background of serious diseases, but also factors not related to the disease. Sometimes it is enough to eliminate the household factor that disrupts the blood supply and the problem disappears on its own. Let's look at the main reasons, not related to illness, why the left hand goes numb.

long hours of work at the computer;
wearing hand-tightening clothing with an elastic band;
hard physical labor;
professions related to handicrafts;
poor and improper sleep: uncomfortable bed, incorrectly selected pillow or incorrect body position;
prolonged placement of the hand above the level of the heart.

Working at a computer is a provoking factor causing numbness in the left hand

In all of the above cases, the hand goes numb periodically, more often after sleep. This problem can be eliminated with the help of gymnastics, massage, and rubbing. Usually this condition goes away within 10 to 30 minutes after waking up or having a massage.

In contrast to the provoking factors that lead to numbness of the left hand, there are a number of diseases for which this symptom is characteristic. In such cases, in order to get rid of this unpleasant feeling, you need to identify and eliminate the cause itself. It is important to note that if the hand goes numb for more than 1 hour, the fingers become numb, pain or discomfort appears in the heart area, breathing is difficult, you need to call emergency help as soon as possible, since such symptoms may indicate the development of a cardiac pathology that is life-threatening.

Diseases that cause numbness in the left hand

If numbness in the left arm is observed too often and is not associated with an incorrect position of the body during sleep, the cause may lie in the presence of some disease, so such symptoms cannot be ignored. Let's look at the main diseases that are characterized by numbness of the left hand:

Coronary heart disease (angina pectoris). Numbness of the left arm is noted in the hand, forearm and shoulder. In addition, a person feels discomfort in the chest and difficulty breathing. You can relieve an attack of angina with nitroglycerin.

Myocardial infarction. Numbness of the left arm is one of the first signs of acute heart failure with subsequent development of myocardial infarction. Quite often, numbness in the left arm becomes the only symptom of a heart attack. Unlike angina, the symptoms of a heart attack are not relieved by nitroglycerin. The only way to save a person’s life is to call an ambulance and then hospitalize the patient.

Atherosclerosis. During the development of atherosclerosis, atherosclerotic narrowing of the arteries that supply the heart and left hand with blood occurs, so numbness of the left upper limb is one of the signs of this disease.

Brain stroke. Acute vascular pathology, accompanied by numbness of the left arm. The appearance of this symptom indicates damage to the right hemisphere of the brain. The patient also has numbness in the left leg, impaired vision and speech.

Numbness of the left hand is a harbinger of heart disease

Osteochondrosis of the thoracic or cervical spine. In addition to the symptoms of the disease itself, there is a loss of skin sensitivity, weakness in the arm, pain and numbness that spreads along the outside of the forearm, shoulder and hand, including the fingers.

Pre-infarction condition. If a person has a history of coronary heart disease, vascular atherosclerosis or hypertension, and suddenly there is a feeling of numbness in the left arm, then do not hesitate to call emergency help. Particular attention should be paid to the little finger of the left hand. If the little finger on the left hand goes numb, the reason for this in 80% of cases is a pre-infarction condition, which often ends in a heart attack.

Thrombosis. Numbness of the left arm appears suddenly, but in addition there is tissue swelling and severe and increasing pain. If such symptoms occur, the person needs hospitalization.

Nervous overstrain. Characterized by pinched nerve endings from muscle tightness, which leads to impaired blood flow and numbness of the limbs

Deficiency of vitamins A and B. Leads to disruption of metabolic processes, damage to the membranes of nerve fibers, which leads to loss of sensitivity of nerve endings and the appearance of numbness.

In addition to the above diseases, the left hand may go numb due to intercostal neuralgia, herniated intervertebral discs, or hypothermia. In any case, it is important to remember that numbness of the left hand cannot be ignored, especially when a person’s history includes pathologies of the cardiovascular system. If this symptom occurs, you must visit a cardiologist, neurologist, or vertebrologist. The examination results will help doctors identify the cause, make the correct diagnosis and prescribe appropriate treatment.

Numbness of the left hand due to osteochondrosis

Numbness in the fingers of the left hand

Based on the above, we can conclude that numbness of the left hand does not always indicate serious pathologies, but if not only the upper limb, but also the fingers are numb, then you should not hesitate to visit a doctor, since such a symptom may be a harbinger of complex diseases. For example, if the little finger on the left hand goes numb, this may indicate a disease of the cardiovascular system. The feeling of numbness is often worse at night, and in the morning a person may feel tingling and numbness from the fingertips and up the entire arm to the shoulder.

Numbness of the fingers is an alarming symptom

If no heart problems are found after examination, the cause may be a lack of vitamins: A and group B. In people over 45 years of age, the hand often goes numb as a result of atherosclerotic changes in the blood vessels.

If the fingers of your left hand—the little finger or the ring finger—go numb, this may indicate damage to the nerve plexuses of the shoulder. In such cases, numbness spreads to the outer part of the arm, weakness in the hand, and pain when bending. If the fingers of the hand go numb in the “index-middle” or “index-thumb” pair, most likely the reason lies in the dysfunction of the intervertebral discs or neck muscles. Then there is weakness in the fingers, pain in the shoulder and forearm. Often this symptom may be present after injury or as a result of surgery.

Numbness in the fingers on the left hand

In any case, determining on your own why your left hand is numb is difficult and almost impossible. Only a doctor, after examination and collected complaints, will be able to identify the cause and prescribe appropriate treatment.

What to do when your left hand goes numb

In order to determine the cause of numbness in the left hand and fingers, it is necessary to conduct a detailed examination of the body. Treatment consists of eliminating the cause itself, only when the disease causing numbness in the hand is eliminated, only then can this unpleasant symptom be eliminated.

My left hand is going numb - only a doctor can determine the cause

In cases where the examination results do not reveal any violations, perhaps the reason lies in an incorrect lifestyle. You need to watch your posture, spend a minimum amount of time at the computer, do exercises daily, eat right, and move more. It is also important to choose the right pillow and bed to make your sleep complete and comfortable. If your left hand has been numb for a long time or other symptoms appear at the same time, you should consult a doctor as soon as possible for qualified help.

Why does my left hand go numb and how can it be dangerous?

In this article we will take a closer look at why the left hand goes numb, what symptoms of diseases manifest themselves this way and how it can be dangerous?

Why does my left hand go numb and why is it dangerous?

The symptom of numbness in the left hand is quite serious.

In order to get rid of this pathological condition, it is necessary to identify the specific cause of its occurrence.

And then you should treat the disease itself, and not just remove its unpleasant symptoms.

Why the left hand and fingers go numb are important reasons for this problem.

Let's take a closer look at the main reasons:

A condition in which the left arm goes numb may indicate that the person is in a pre-stroke state. Because the cause of numbness may be poor circulation in the brain, poor circulation can clearly indicate the risk of a stroke. In this case, a person, as a rule, has the problem of high blood pressure and high cholesterol levels in the blood.
Numbness of the left hand may indicate that there is a threat of a heart attack, especially if the state of numbness of the left hand and fingers is accompanied by pain in the heart and increased blood pressure.

Numbness may be due to a previous injury (bruise, fracture, sprain or torn ligament)
It is also possible that there is inflammation in the ulnar nerve.
Too much physical activity and working for quite a long time in an uncomfortable position also leads to the muscles becoming overstrained, pinched, and all this causes a feeling of numbness in the fingers and hand.
If you look from the nervous system, numbness can clearly indicate that the nutrition of the muscles is impaired due to the fact that the nerve endings are compressed.
In addition, any numbness indicates that there is a problem in the spine: when blood vessels and nerve endings are compressed, when there is osteochondrosis, then all this ultimately leads to numbness.
Another cause of numbness may be a disease such as spinal tuberculosis.
Numbness may indicate that there is an oncological problem. When, for example, there is a tumor in the spinal cord, and it progresses (grows), it begins to put intense pressure on the nerve endings located nearby. As a result, unpleasant symptoms appear, as if the hand and fingers are going numb.
A fairly common cause of numbness is ordinary fatigue due to the fact that physical and/or mental stress is excessively high. In this case, your “doctor” is a good rest, and the best thing is sleep. Massaging numb limbs will also help.
Often, severe overstrain in the muscles of the cervical-collar region leads to numbness of the hand and fingers. Pianists and those who work a lot at the computer often suffer from this problem, as they spend a long time in the same unnatural position for the head and body. All this leads to great overstrain, spasm of blood vessels and muscles, compression of nerve endings, and, as a result, pain and numbness.
It often happens that the left hand goes numb due to the fact that the person fell asleep in an uncomfortable position and, as they say, “stuck” the hand. In this case, a tingling sensation is clearly felt in the arm and fingers, as well as in the palm.
Very often, sudden and severe stress causes spasms in blood vessels and muscles, and this leads to numbness in the hand and fingers.
Often this problem (in the form of a side effect) appears because a person is using any medications.
Fingers, palms, arms and shoulders often go numb because the body suffers from a lack of water, that is, the body gives a signal about dehydration.

Why do the fingers of my left hand go numb?

Causes of numbness in fingers:

Sometimes numbness in the fingers occurs due to low blood sugar levels or lack of B vitamins.
Fingers often go numb during headaches, dizziness, and before loss of consciousness.

Numbness in the fingers may be due to an injury and damage to the nerve fibers in the wrist area (in this case we are talking about carpal tunnel syndrome). In the presence of this syndrome, a person feels pain, a tingling sensation and weakness of the hand muscles.
A common cause of numbness and tingling in the fingers is hypothermia, lack of vitamins, frequent interaction with quite harmful substances and frequent alcohol consumption.
Often the cause of numbness in the fingers can be nearby organs and tissues. For example, any previous surgery, any disease, viral and infectious lesions of the body, all this can cause discomfort.

Numbness of the little finger of the left hand

This often happens due to the fact that a person works at a computer, and the hand is in the same state of tension for a long time.

The little finger also becomes numb because a person does monotonous work for a long time.

Another common cause of numbness in the little finger is “tunnel syndrome,” which develops due to compression of the nerve endings.

As a result of the nerves being pinched, a so-called “tunnel” is formed, in which all the nerve endings find themselves.

If you hold your hand in the same position for a long time, the compressed nerve causes severe tension, a feeling of pain and tingling, sometimes even a slight trembling, as well as numbness.

If such discomfort occurs, you need to intensively rub or massage the entire hand, and also perform several simple movements - bend the hand and fingers, straighten it, rotate the hand, etc.

If numbness of the little finger occurs due to the presence of cardiovascular diseases, as well as diabetes mellitus, atherosclerosis, etc. , then there is no need to self-medicate under any circumstances!

If the little finger systematically goes numb, then you should definitely consult a neurologist, therapist and cardiologist.

Why does the ring finger on my left hand go numb - what should I do?

If the ring finger on your left hand goes numb, then it is necessary, first of all, to check the functioning of the heart and blood vessels.

Loss of sensitivity in the ring finger may be due to the fact that the body lacks vitamins, especially vitamin A and B vitamins.

Only a specialist can tell you what exactly is the cause of numbness after a thorough examination.

Numbness of the thumb on the left hand

Numbness of the thumb on the left hand occurs due to the fact that the normal functioning of the respiratory system is disrupted.

When a feeling of numbness affects two fingers on the hand at once, for example, the thumb and middle (or index) finger, this most likely indicates that there is a displacement of the intervertebral discs or the nerve endings in the cervical spine are compressed.

In this case, you will feel, along with numbness, a feeling of weakness, pain in the forearm and shoulder.

Also, numbness of the thumb on the left hand may indicate that there is an inflammatory process in the internal organs, usually in the liver, kidneys or lungs.

Numbness of the index finger on the left hand

When the index finger is numb, there is often inflammation of the nerve endings of the shoulder or elbow joint.

In this case, numbness of the finger is always accompanied by weakness of the arm, pain when bending it and numbness on the outside of the arm.

Systematic and very long-term monotonous movements, which are performed due to professional duties, quite often lead to the fact that the index finger becomes numb, severe stiffness appears in the hand, and convulsions (spasms) appear.

Numbness in the palm of the left hand

This numbness often manifests itself in the morning. And the reason for this is a very uncomfortable posture during sleep.

But it also happens that numbness in the palm begins without any apparent reason.

In this case, you should immediately go to see a doctor in order to rule out very serious pathologies in the body.

Numbness of the palms during sleep (at night) may be due to the fact that there are disturbances in the functioning of the endocrine system or in the functioning of the nervous system.

And the most common reason for this is osteochondrosis of the cervical spine. The peculiarity of this disorder is that only one hand goes numb, and not two at once.

If you suddenly feel that your left hand is going numb, and the numbness is spreading from bottom to top, and at the same time a feeling of pain begins, which only intensifies over time, then you need to urgently contact the emergency department, as in this case arterial thrombosis is possible.

Why does my left forearm go numb?

Numbness of the left arm to the level of the elbow (when only the forearm is numb) may be associated with poor blood circulation in this area due to injury, due to an uncomfortable position or strong and regular overexertion (especially during monotonous movements), as well as hypothermia.

As a rule, numbness in these cases is not permanent, and they go away quite easily after a light massage or physical warm-up.

Numbness in the forearm can develop against the background of the presence of osteochondrosis and disturbances in cerebral circulation, as well as with diseases of the internal organs, due to severe stress, etc.

Feeling of numbness in the left arm during pregnancy

During pregnancy, numbness of the left hand may be associated with osteochondrosis or other diseases (damages) of the spine.

Pregnancy is precisely the period when all existing diseases begin to worsen, and those diseases that were still hidden begin to appear.

Often a lack of vitamins or minerals, especially the trace element iron, causes numbness.

A pregnant woman gains weight a little every month.

At the same time, her motor activity gradually begins to decrease. This can cause poor blood circulation, and, as a result, the cause of numbness in the left hand.

In the third trimester of pregnancy, the risk of swelling is very increased, and it is during this period that many pregnant women complain that their fingers are numb (especially the little finger and ring finger).

What to do if your left arm, fingers or palm goes numb?

First of all, you need to see a good neurologist. It would be a good idea to visit a cardiologist, a therapist, and perhaps even a surgeon.

In any case, your treatment should begin with a consultation with a specialist to find out the exact causes of your discomfort.

If you do not delay this issue and consult a doctor in time, then numbness in your hands and fingers can be quite easily cured.

The basic principle of treating numbness is to restore all functions in the nerve endings and restore good blood flow.

For this purpose, physical therapy (physical therapy), massage and physiotherapeutic procedures are used, as well as the necessary drug treatment, which is prescribed exclusively by a doctor!

As a rule, before making a diagnosis, the doctor prescribes examinations in the form of MRI (tomography) and X-rays, as well as ultrasound.

If there is such a need, the patient is sent to inpatient treatment.

Measures to prevent numbness in the left hand

To prevent all those diseases that provoke numbness in the left hand, first of all, you should give up any bad habits, such as smoking and drinking alcohol - first of all.

It is necessary to lead an active, healthy lifestyle and seriously adhere to a healthy and natural diet.

Unhealthy diet, unhealthy lifestyle and bad habits ALWAYS lead to a disturbance in the circulatory system and, as a result, blockage of blood vessels and the formation of cholesterol “plaques” on their walls, which is the cause of numbness in the FIRST PLACE!

Now you know why your left hand goes numb and how it can be dangerous for a person.

The left arm goes numb (paresthesia) - we are looking for the causes of numbness

Paresthesia - what is it?

The human body is a complex, ideally integral system that responds to the slightest changes in the internal and external environment, manifesting itself in a number of signs and pathologies that affect the quality of our life.

One of these signs is called paresthesia in medicine - this is when the left arm, right, or other parts of the body go numb. Besides the fact that paresthesia of the left upper limb is a very difficult condition, accompanied by a feeling of tingling and crawling, it does not occur by itself, but is a primary sign of quite serious diseases.

Causes of paresthesia - why does my left hand go numb?

The genesis of this condition is due to a violation of skin sensitivity as a result of radicular irritation or compression of nerve fibers, thereby disrupting the transmission of nerve impulses.

Based on the localization of the pathological process, one can determine the reason why, for example, the left arm from the shoulder to the very tips of the fingers goes numb.

In addition, this condition may be accompanied by:

Signs of hypalgesia (decreased sensitivity threshold);
Skin cyanosis (blue discoloration of the skin), which may be an indicator of a lack of oxygen in the blood and a sign of pathologies of the cardiovascular and respiratory systems;
A feeling of coldness in the hand, evidence of disturbances in the circulatory system or disorders of the nervous system;
A painful symptom in the hand, often indicating a myalgic impulse syndrome from inflamed and damaged areas.

Many patients note a loss of sensation in the hand during night sleep or immediately upon awakening. This can be explained by prolonged stay in an uncomfortable position, which causes impaired blood circulation in the limb. Muscle hypertonicity and disruption of the continuous process of blood circulation can cause numbness in the left arm from the elbow to the hand, which cannot be associated with any disease.

You just need to choose a comfortable orthopedic pillow and the problem will solve itself. But loss of sensation in the hand, manifested against the background of vascular pathologies or vertebrological disorders, is already a problem.

What diseases lead to numbness in the hand and fingers?

the little finger on the left hand goes numb, photo

The main causative factors causing signs of paresthesia of the extremities include a number of internal pathologies.

Heart and vascular diseases

In almost 85% of patients, the feeling that the left hand is numb in the little finger and ring finger is the main indicator of cardiac diseases - acute coronary syndrome, CHF (chronic heart failure), followed by damage to the heart muscle (heart attack).

This may be an ischemic pathology in the form of angina pectoris, the symptoms of which include heart pain, numbness in the left arm, discomfort in the chest and difficulty breathing. The feeling of paresthesia of the arm intensifies at night, and in the morning the symptoms are manifested by numbness and tingling of the entire surface of the limb from the shoulder to the fingertips. If such symptoms last more than an hour, do not postpone your visit to the doctor.
If the left or right hand, including the fingers, goes completely numb, combined with speech, visual impairment and difficulty moving, a clear sign of a stroke is diagnosed. Moreover, if loss of sensitivity is noted on the left side, this indicates disturbances in the processes of cerebral circulation in its right hemisphere. Failures in blood circulation in small vessels provoke paresthesia in the left hand and numbness in the fingers
The combination of paresthesia symptoms with high blood sugar levels is characteristic of diabetic polyneuropathy, which can result in gangrene of the fingers. Acute vascular pathologies caused by atherosclerotic narrowing of the arteries (atherosclerosis) also cause disturbances in the sensitivity of the upper extremities.

In patients over 45 years of age, paresthesia of the extremities is provoked by:

Thrombosis processes;
Atherosclerotic process in the vascular walls provoked by pathological changes due to vitamin deficiency (deficiency of vitamins “A” and “B”);
The inability of adequate blood flow, caused by muscle tightness due to nervous strain, can cause a feeling of numbness in the left hand, little finger and ring finger.

A classic example of a disease that causes loss of sensitivity in the shoulder girdle (numbness of the left arm) is brachial plexitis. It can in turn be provoked by:

Pathologies of purine metabolism (gout);
Diabetes and alcohol syndrome;
Injuries and wounds of the shoulder;
Musculo-ligamentous tears and sprains;
Injury to the wrist and scapula;
Compression-ischemic neuropathy syndrome (tunnel);
Cystic neoplasms in the nerve ganglia, causing numbness in the fingers and little finger on the left hand;
Syndromes - “Raynaud’s” (ischemia of the hand) and cubital (compression of the elbow nerves).

The development of paresthesia is a common problem with:

Tendobursitis caused by articular inflammatory reactions in the shoulder. Accompanied by severe pain in the shoulder region radiating to the cervical area and shoulder girdle.
The presence of cervical osteochondrosis, characterized by degenerative processes in the vertebral discs, provoking radicular pinching of nerve fibers and causing paresthesia of the limb, pain when moving the neck, arms and shoulders.
Cervical spondylosis is a pathological process in the spine caused by bone growths on the vertebrae. Paresthesia is accompanied by occipital pain syndrome, which intensifies with the slightest movement.
In scalene muscle syndrome, arterial compression of the brachiocephalic trunk causes radicular irritation of the nerve fibers of the brachial plexus. The muscle tissue is compressed and pressed against the thoracic vertebrae, causing weakness, tenderness and left-sided paresthesia.

To all these factors we can safely add neuralgia of the intercostal nerves, intervertebral herniated formations and the hypothermia factor. This suggests that the variety of causes completely excludes self-diagnosis and self-medication, and requires qualified help.

Moreover, when it is clarified, ordinary living conditions may well turn out to be the only provocative factor of the disease, the elimination of which will correct the situation.

Causes of numbness in the hands of a domestic nature

Paresthesia in the left hand can develop for completely different reasons, independent of pathological processes in the body. May be a consequence:

Daily, routine work associated with manual printing;
Hand squeezing by clothing (elastic inserts);
Natural physical fatigue;
Specifics of the profession (painter, plasterer, embroiderer, etc.);
Uncomfortable bedding, causing a forced long position during night sleep;
Holding the limb in an elevated position (at shoulder level) for many hours.

In such situations, the easiest way to get rid of paresthesia is to eliminate the causative factor or periodically stretch the arm with massage, rubbing, or gymnastic exercises.

Treatment of paresthesia - what to do if your left hand goes numb?

In each specific case, the problem of loss of hand sensitivity is solved by doctors - cardiologists, neurologists or vertebrologists. Such symptoms cannot be ignored, especially for those who are susceptible to cardiovascular diseases.

Modern diagnostic techniques will help to quickly identify the causative factor. To identify the cause, the following is prescribed:

MRI examination of the spinal cord/brain;
Dopplerography of the vessels of the cervical area;
X-ray examination of all parts of the spine;
Rheovasography – diagnostics of blood circulation in the arm;
Electroneuromyography – a comprehensive examination of the neuromuscular system;
Blood test for toxins.

The therapeutic treatment plan is drawn up in accordance with the identified pathology. If none is found, the course of therapeutic treatment consists of drugs that have a positive effect on sensitivity disorders.

The treatment course includes “Trental”, “Nicotinic acid”, “Paracetam”, “Actovegin”, vitamin complexes.

To restore sensitivity, physiotherapeutic techniques are used - magnetotherapy, electrophoresis, dynamic currents and mud therapy.
