For everyone, there may come a time when one morning, washing oneself, suddenly you begin to understand that the nail phalanx is practically not felt on the ring finger or any other finger. Immediately the thought of cold water comes to mind. But when you turn on hot water, but there are no changes, you understand that fingers are numb. What are the causes of this phenomenon, and what to do?
Fingers grow numb: to panic or do nothing?
The state in which the loss of sensation is felt in the fingertips is probably familiar to everyone since childhood. It was observed when unrestrained snow battles took place, and the hands, although in mittens, were soaked and frozen so that a painful aching in the fingers and their numbness appeared.
In such cases, this is not considered a pathology and passes on its own within a few minutes, when the mechanism for triggering the loss of sensitivity is removed or removed. But if fingers are exposed to too low temperatures, it is possible to get damage in the form of frostbite.
In addition to cold weather, there are many other factors that can affect the sensitivity in the fingers. Some of them may simply be muscle fatigue, while others may be a symptom of the disease. The main cause of numbness in the tips of the fingers is the impact or damage to the nerve, which, in turn, indicates a more serious problem that cannot be resolved without a doctor.
So why are the fingers numb and is it related to some disease? Let's take a closer look at this.
Excessive load on ligaments and muscles
After exercise or exercise, which involves the hands, and the ligaments and muscles are very tense, the blood flow to them is increased. The periphery - the tips of the fingers, on the contrary, receive less blood, which is manifested by numbness.
Quite a common cause of numbness of the fingertips. Insensitivity is experienced because the body is exposed to very low temperatures, and blood vessels are compressed to prevent heat loss. This leads to a decrease in blood supply in parts of the body that are exposed to cold, which causes numbness. Frostbite is quite dangerous and can lead to serious complications.
Nerve fiber problems
A pinching of the nerve causes his abnormal work, which is manifested by numbness and tingling. There may be many reasons for this:
- herniated disc;
- malignant neoplasm;
- injury, etc.
This condition occurs with diabetes. Uncontrolled levels of sugar in the body prevents the corresponding flow of blood to the nerves of the body and causes their damage, thereby leading to loss of sensitivity. This condition causes numbness and tingling in the fingers. Nerve damage can be prevented by controlling blood sugar levels.
Carpal tunnel syndrome
This condition is inherent in people who work a lot with their hands. These are musicians, computer operators, typists, tennis players and others. In these cases, the median nerve is pinched between the bones and the tendons of the muscles on the wrist, which leads to numbness of the hand and fingers.-
A rather rare disease in which the blood vessels of the fingers become narrow due to spasms, as a result of which a violation of the blood flow to this area occurs, causing numbness in the tips. The affected area can become bluish or pale.
Insensitivity disappears as soon as normal blood flow is restored. This situation usually occurs in rheumatoid arthritis, atherosclerosis, scleroderma and other similar diseases.
This is a disease of the arteries and veins of small and medium diameter, which is caused by insufficient blood supply due to the swelling of blood vessels and their subsequent blocking by blood clots. The first stage of the disease is characterized by tingling and burning in the finger tips. One of the etiological factors that trigger pathogenetic mechanisms is tobacco smoking.
Uncomfortable position during sleep
Inconveniently lying hands, especially when thrown over the head during sleep, can cause clamping of nerves and blood vessels. That is why both the fingers on one's hands grow dumb, and the entire hand as a whole falls asleep.
In addition to these reasons, the following pathologies can cause numbness in the fingertips:
- multiple sclerosis;
- panic attack;
- vitamin deficiency;
- systemic lupus;
- pernicious anemia.
How to be and what to do?
Consultation with a specialist is necessary to treat a condition with numb fingers, since, as can be seen from the above, a change in the position of the hands is not always sufficient. There are such methods of therapy as:
- diagnosis and treatment of the underlying disease;
- applying ice and massage in the place of loss of sensitivity in order to stimulate blood flow;
- the use of nonsteroidal anti-inflammatory drugs for carpal tunnel syndrome to reduce pain, surgical intervention is not excluded;
- medication that improves blood flow and strengthens blood vessels;
- rejection of bad habits;
- the use of drugs that prevent the formation of blood clots in the vessels;
- sugar control in diabetes;
- in the case of non-receipt of nutrients in the proper amount - a change in lifestyle and diet;
- reducing the load on the spine and providing optimal conditions during the night;
- with large loads on the wrist, it is necessary to take periodic breaks and exercises for the hands.
Summing up, it should be noted that people who have numbness in their fingers should lead a healthy lifestyle, eat a good and balanced diet, regularly perform exercises, get a good rest and have enough sleep. Exposure to extreme cold temperatures should also be avoided. Mandatory refusal of tobacco and alcohol. If numbness, tingling and burning in the finger tips occur, you should consult with a specialist. Take care of yourself and your health!
