It is quite natural that a person has freedom of movement, he fully owns his own body - this is necessary for normal life. However, not many of us have thought about the fact that this requires the correct functioning of a huge number of systems. It is worth appearing at least a small malfunction in the work of this well-established “machine”, and we are frightened by the fact that we are no longer the masters of our own hand or foot. Therefore, quite often patients turn to the doctor with complaints that their hands are numb. We will try to analyze the reasons for this phenomenon in this article.
System failure
Let's list some of the most common causes of hand numbness.
1. Osteochondrosis. This disease damages the cervical spine, and if the patient additionally has a disc herniation, then a situation occurs when the nerve roots of the spinal cord are simply pinched. The patient may feel a crunch and pain in the neck, general weakness and numbness of the hands. All kinds of neuritis, plexitis, which appear with fractures of the hands, with dislocations of the joints, often provoke false sensations - paresthesia.
2. If the hands go numb, the reasons may be the malfunction of the small branches of the nervous system. Maybea spasm in the small vessels of the hand appears - Raynaud's disease. A clear sign is that the fingers and hand suddenly turn blue or white, and also lose their sensitivity. Most often this happens due to diseases such as systemic lupus erythematosus, rheumatoid arthritis, etc. But there are times when the cause simply cannot be identified.
3. If the hands go numb, the causes may be circulatory failure. Therefore, patients with such a complaint should observe their own habits and postures. You can pinch the blood vessels with your arms constantly crossed on your chest, with an unnaturally turned neck … An excess of lactic acid and a lack of oxygen in the muscles often provoke numbness in the hands. The same symptom occurs in patients with anemia and diabetes.
4. If the hands go numb, the causes can be hidden in malnutrition of tissues, inflammatory or degenerative changes in the vessels and nerves. Also, for this reason, the patient may develop chronic hypovitaminosis.
Leg goes numb - reasons
Numbness of any limb in the first place may indicate improper circulation. Blood brings both oxygen and glucose to the tissues. If the blood enters in small quantities or stops flowing at all, this affects the state of he alth very quickly. The pump that pumps blood around our body is the heart. It just so happened that it is the legs that are located farthest from the "pump", therefore, circulatory disorders are most often found in the lower extremities. So the most common and most basicthe cause of leg numbness is disturbances in the blood supply to the vessels.
- Hypothermia can disrupt the blood supply to the legs. Therefore, warm shoes in winter are a must. Numbness in hypothermia always begins with the fingers. Measures should be taken immediately to warm the toes. For example, you can take off your shoes and get a massage.
- Legs can become numb with diseases of the cardiovascular system. If the heart does not cope well with its functions, various parts of the body can suffer from this. There may be problems in the vessels themselves. People with diabetes should be especially wary.
- With diabetes, a diagnosis called "diabetic foot" is possible, in which the blood almost stops flowing to the tissues of the feet, and they become numb.
- If you sit on the leg for a long time, it also becomes numb, but as soon as the blood circulation returns to normal, the problem disappears.
