Numbness of the hands (paresthesia) is the most common complaint when contacting a doctor. It is accompanied by unpleasant sensations in the hands and fingertips in the form of goosebumps, tingling, and so on. The term "numbness" implies a partial or complete lack of sensitivity in a certain part of the body with damage to the nerve or impaired function.
The causes of paresthesia can be frostbite (with damage to the skin, muscles and blood vessels), as well as circulatory disorders, which can be caused by various factors, as a result of which the arm (left) is numb, and the little finger of the left hand is numb. If frostbite is an obvious cause, then all other factors, including circulatory disorders, can be detected only by a medical examination and medical examinations. The diagnosis can be diabetes and compression of nerves or blood vessels.
One of the most common causes of numbness in the fingers is osteochondrosis, a complex dystrophic disorder in the articular cartilage. Finger paresthesia can be a sign of cervical osteochondrosis. If the little finger of the left hand is numb, as well as the ring finger, this indicates a dystrophic disturbance in the joints of the lower cervical spine. To be more precise, there is a problem in the eighth cervical vertebra, squeezing the seventh and eighth cervical roots.
If the little finger of the left hand is numb and there is a slight tingling sensation, this is a sign that the nerve was compressed for a short while. To get rid of an unpleasant sensation, you just need to change the position of the hand, while the functions of the nerve should be restored. Usually this symptom is characteristic of older people, since during this period of life problems with the nervous system are accompanied by diseases of the heart and blood vessels. Therefore, the functions of the nerves are not able to quickly recover after infringement, as was the case in young years. For comparison: if pressure on a nerve occurs with equal strength in a young and an elderly person, numbness is more likely for the latter.
During the day, various cases of numbness of the fingers or hands may occur. This can be due to an uncomfortable position of the person’s arms and body in transport (if he has to hold onto the handrail) or after sleep. Numbness of two hands occurs quite rarely and may not last long. But when one hand goes numb, this process can be lengthy and often repeated. If the feeling that the little finger of the left hand is numb, occurs regularly, then you need to seek medical advice and undergo the necessary examinations. This will help the doctor clarify the cause of the problem and prescribe adequate treatment.
Without the conclusion of a doctor who has on hand the results of your examinations, it is impossible to determine why the left arm is numb . After all, numbness of the left hand can be a signal of a pre-stroke state. With similar symptoms, of course, other diseases are possible. For example, it can be neuritis of the ulnar nerve, problems with the musculoskeletal system, a disease of the cardiovascular system or nerve trunks. If you feel discomfort in the left hand, which does not go away for a long time or for some reason is constantly renewed, you should definitely consult a doctor.
In order for the doctor to find out why the left hand is numb, the causes of this phenomenon, the patient needs to tell him about all his feelings, up to indicating the date preceding the numbness, about the nature of the work in which this happened, the duration of the phenomenon. If symptoms appear at a certain time during the day, then this information must be reported to the doctor. In addition, any symptoms related or not associated with numbness must be described. Only a qualified, experienced doctor will be able to identify the reasons why the little finger of the left hand or the hand itself is numb and prescribe the correct treatment.
