Unpleasant sensations such as tingling in the fingers, numbness, and “goosebumps” periodically occur to each of us. This condition is most often associated with temporary compression of the nerve, for example, during prolonged stay in an uncomfortable position. Hands become numb when they are bent or raised, if you hold onto a handrail for a long time in transport, when wearing tight clothes, or when working on a computer. As soon as you change your position, the numbness and tingling in your fingers disappears.
It’s another matter if unpleasant symptoms appear more and more often. In this case, it is necessary to go to the hospital for examination, since such signs indicate the development of neurological diseases.
“Goosebumps” and tingling in the fingers occur when nerves in various parts of the body are compressed or irritated.
If a nerve in the cervical spine is pinched, a radicular syndrome develops, in which patients complain of numbness and tingling in the hands. There are several reasons for the appearance of the syndrome - cervical osteochondrosis, spina bifida, tumors, lateral displacement of the vertebrae, spondyloarthrosis, infectious lesions (tuberculosis, osteomyelitis)
Compression of the ulnar nerve leads to cubital syndrome, the symptoms of which are pain, numbness, weakness in the hands, tingling in the fingers, namely the little and ring fingers. This syndrome develops from frequently repeated bending of the arm at the elbow, with emphasis on the inner parts of the elbows, improper fixation of the arms when working on a computer, and prolonged stay of the arm in a bent position, for example, in sleep. Often the appearance of the syndrome is due to the specifics of the profession, in which there is excessive exposure to the ulnar nerve. Another reason for the development of cubital syndrome may be a thickened nerve - in this case, the walls of the canal put pressure on it. It must be said that the size of the canal is such that the nerve barely fits between the bone and the ligament, and the slightest external influence can lead to disruption of its functioning. At first, unpleasant sensations arise only with prolonged exposure to the ulnar nerve, but as the disease progresses, these signs become more pronounced and are constantly present. Refusal of treatment leads to atrophy of the arm muscles.
Another reason that causes tingling in the limbs is carpal tunnel syndrome. Its development is caused by compression of the median nerve in the carpal tunnel. Most often this is due to work in which you have to constantly make the same movements with your hands. The work of packers, pianists, and those whose work involves working on a computer. Other factors leading to carpal tunnel syndrome: arthritis of the hands, swelling of the hands due to fluid retention in the body, for example, during pregnancy, tumor, diabetes, thyroid dysfunction, wrist injuries. The disease is initially mild and does not cause concern, but gradually pain and tingling in the fingers and palms become more and more noticeable. Lack of treatment leads to atrophy of the thumb muscles.
Numbness and tingling in the fingers can occur when the nerve roots and trunks in the brachial splenten are compressed - scalene syndrome. Patients complain of pain in the shoulder and arm, weakness, numbness and tingling in the hand, especially in the little finger and ring finger, and sometimes chilliness in the limb. When you tilt your head, these sensations intensify. The cause of the syndrome is cervical osteochondrosis, in which irritation of the nerve roots occurs, causing reflex muscle spasms. As a result of muscle spasm, the subclavian artery and brachial plexus are compressed.
Numbness and tingling of the hands can be associated with stroke, multiple sclerosis, infectious and heart diseases, lack of vitamins, malnutrition, and injuries.
In any case, you should consult a doctor to make a correct diagnosis.
