Why fingers grow numb: possible causes

Why fingers become numb: possible causes of

Numbness in the fingers is an unpleasant symptom that is observed in young as well as elderly people. It is typical for many diseases, but it can also indicate minor disturbances in the body. In any case, if fingers become numb, consultation of the doctor is necessary. Self-medication in this case is unacceptable, because often such a symptom is a sign of cardiovascular system disorders.

External causes of

Not always numb fingers indicates the development of pathologies. If this symptom is observed only in the morning hours and passes independently a couple of minutes after awakening, then the reason for this may be the transmission of arteries. Most often, this happens with an uncomfortable position of the body during sleep or in those cases when a person forgets to remove all the compressive objects from the fingers and wrists( rings, bracelets).

To the unpleasant sensations quickly passed, you just need to perform in the morning, without getting out of bed, simple exercises. Raise your hands up and begin actively bending and unbending your fingers until the discomfort at your fingertips disappears.

It is also worth noting that an unpleasant tingling in the fingers of the upper limbs can occur as a result of wearing tight clothing. It squeezes the arteries, thereby violating the blood circulation, which causes the appearance of this symptom.

Pay attention to the clothes that you wear during the day and at night. If it has elastic bands or it has a close cut, then it is better to abandon it. In addition, you need to carefully examine your sleeper. If it has dents or knobs, it can also lead to numbness of the upper limbs.

External causes

It's worth worrying when the fingertips are numb all the time. This symptom does not disappear throughout the day, even if you wear loose clothing. This already indicates serious disorders in the body that require immediate treatment.

Internal causes of

Pathologies that are characterized by numbness of the fingers are many. The most common of these are:

  • osteochondrosis;
  • carpal tunnel syndrome;
  • polyneuropathy;
  • Raynaud's disease;
  • thrombosis;
  • occlusion of cerebral vessels.


Osteochondrosis is a disease in which dystrophic disorders occur in the articular cartilage. When this disease affects the cervical region, nerve endings that lead to the upper limbs are damaged.

The main sign of the development of osteochondrosis is the periodic numbness of the fingertips. And it is observed only on one hand - either on the left, or on the right. With osteochondrosis, all upper limbs do not go numb at once, and discomfort does not spread to all hands( only fingertips).To make the correct diagnosis, you need to undergo a comprehensive examination.

Carpal tunnel syndrome

This condition is characterized by pinching of the middle nerve in the wrist. With the development of such a disease, a person not only notes swelling of the fingers, but also their soreness. Often the pain is so severe that it prevents him from engaging in daily activities.

In most cases, people suffer from this pathology, which often have to stay in one position for a long time( for example, when working on a PC).At this moment they have very strained hands and blood circulation is disturbed in them. Therefore, if you due to your professional activities have a long time to sit at the computer, remember that you need rest. Every 50-60 minutes, do a warm-up. This will avoid stagnant phenomena and jamming of nerve endings.

Carpal tunnel syndrome


Polyneuropathy is characterized by damage to the nerve plexuses of the hands and fingers. Such violations in the body often lead to the appearance of such an unpleasant symptom as numbness of the right arm or left.

The frequency of this symptom varies. It depends on the degree of damage to the nerve plexuses. A tingling sensation can be observed several times a day or a week. Polyneuropathy develops on the background of infectious diseases, iron deficiency anemia or vitamin deficiency.

Raynaud's Disease

Raynaud's disease leads to a violation of blood circulation in small vessels of the circulatory system of the fingers. It is characterized by the simultaneous numbness of the left and right hands. In this case, people who are ill with Raynaud's disease, going out into the cold immediately begin to freeze and often suffer from infectious diseases.

This disease requires special treatment, so it is not worthwhile to delay the approach to the doctor, as this can lead to serious complications. In addition, people with such a disease is not recommended for a long time to keep hands in the cold, and also in contact with water and household products should always be worn on the hands of household gloves.


Thrombosis of the upper limbs is a disease in which blood vessels clog the blood clot, resulting in impaired blood circulation. The fingertips cease to receive the necessary amount of blood and nutrients, and therefore begin to grow numb.

At the initial stages of the development of the disease, only numbness of the fingertips is observed, after which the unpleasant symptom spreads to the entire hand, and it becomes even more intense.

Important! If numbness of fingers does not occur after 1-2 hours, then immediately consult a doctor! Otherwise, against the background of this disease, tissue necrosis may develop and if untimely medical care can be simply lost limb.

Brain obstruction of the brain

This condition can also lead to numbness of the fingertips. However, in this case, this symptom indicates the approach of a stroke. With such a disease a person experiences discomfort in only one hand, but at the same time he is also concerned with headaches and high blood pressure.

If these symptoms occur, it is also important to seek help from a doctor in time. After all, this disease can lead to death.

Corking of cerebral vessels

There is one more state that we did not specify in the list. This is the "lover's syndrome".It is not a pathology, but it can cause numbness in fingertips. This syndrome occurs when a woman sleeps on the man's arm throughout the night.

His hand is stationary for a long time, and the head of a woman leads to a strong squeezing of blood vessels. As a result, the numbness of the fingertips may not last a long time.

Other causes of

It is important to note and the fact that if you have numb fingers of a cause, you can hide in other systemic disorders in the body. For example:

  • upper limb injury;
  • of the endocrine system;
  • arthritis or arthrosis.

In such conditions, in addition to numbness of the fingers, other symptoms are noted. With rheumatism, joints and muscles are affected, as well as the cardiovascular system. Such a disease is often accompanied by severe pain in the fingers and an ache.

In the presence of endocrine diseases, people can have rapid weight gain, inflammation of the lymph nodes, as well as general deterioration of well-being.

With arthrosis and arthritis, pain is felt when the fingers move. It is also possible the appearance of swelling of the fingers and a change in their shape.

We have not accidentally included in this list injuries of the upper limbs, as they too can cause numbness in the fingers. They can be obtained not only with a bruise or fracture, but also during surgical intervention. This syndrome occurs as a result of circulatory disorders. And even if the trauma was received long ago, she still can remind a person about herself and after a few years.

To establish the exact reason why fingers become numb, only an experienced doctor will be able to. After all, in this case, an important role is played by the hand on which this symptom is observed.

Numbness of the fingers of the left hand most often speaks of cardiac pathologies or dystrophic changes in the spinal column. But dumb fingers of the right limb can testify to diseases of the upper respiratory tract or hypercholesterolemia. In any case, you can not do without a special examination and help from a doctor.

What should I do if my fingers become numb?

Are you wondering what to do if the finger tips grow numb? Immediately make an appointment with a doctor! Only he can determine the cause of this unpleasant symptom and prescribe the appropriate treatment for you.

Do not self-medicate for one simple reason that you can not independently establish a factor that causes numbness in your fingers. And if you tighten with treatment, then there may be serious complications.

What to do if your fingers grow numb

Before going to the doctor, you can ease your condition by performing simple procedures. First, start to rub the fingertips until the skin on them blushes, and the unpleasant symptom does not disappear.

If this does not work, then you can use a contrast shower. The change in water temperature will improve blood circulation and relieve discomfort. However, remember that prolonged exposure to cold temperatures can exacerbate the disease if it comes to arthritis or arthrosis.

Do not use any external medicinal creams or ointments unless they are prescribed by a doctor. And do not need to look for information on the Internet, why there is numbness in the hands. You can get exact information about this from your doctor only.

Prevention of numbness in the fingers

It is recommended to conduct preventive measures for numbness of the fingers, especially for those who lead a sedentary lifestyle and work for a long time at the computer.
Prevention includes simple exercises for which you will have to leave for 5-10 minutes a day. So, let's begin.

Immediately after awakening, without getting out of bed, raise your hands up, clench your fists and begin to unclench and compress them about 40-50 times. Then get out of bed, turn your face to the wall, go up on your toes and raise your hands up. In this position, you must stay at least 2 minutes.

Then press your palms against each other, cross your fingers, squeeze them hard, and then unfasten. Do this exercise 10-15 times. For the effectiveness of preventive measures, it is recommended to perform such exercises 2 times a day - in the morning and in the evening just before bedtime.

And lastly I would like to note that the numbness of the fingertips often occurs due to disorders of the brain and central nervous system. Inactivity in this case can lead to either a disability or a fatal outcome.
