Loss of finger sensitivity is quite common. The appearance of a sensation of numbness is observed in the case when a person has been in one position for a long time, and the vessels of the hand have been temporarily squashed, for example, during sleep. In this case, a feeling of numbness is considered a physiological norm. After some time, after several movements, everything is normalized. Another thing is if the fingers (or finger) numb often. We learn the opinion of experts about why the thumb on the right arm is numb.
Causes of Numbness in the Thumb
The reasons for which the thumb of the right hand is numb is somewhat. The most common are:
- Syndrome carpal (carpalny) channel, arising from the compression of the nerve, passing through the wrist with a prolonged load on the muscles and wrist joint. This syndrome is typical for people of certain professions, including seamstresses, painters, violinists. Often, with excessive strain on the tendon, the finger of the right hand (as, indeed, other fingers) dumbs when working on a computer for a long time. The syndrome and those who play computer games using a computer mouse are also affected. Syndrome of the carpal canal can be observed with arthritis, arthrosis, hemangioma, neurofibroma. Numbness of the thumb is often combined with loss of sensitivity of the middle and index fingers.
- Osteochondrosis or a hernia with compression of the nerve end in the vertebrae C6 of the cervical spine.
- Postponed physical trauma.
In some cases, the thumb pad of the right arm is numb. Experts warn: the tip of the thumb on the right arm becomes numb with the beginning of arteriosclerosis of the vessels or inflammation of the joint.
Prevention and treatment
Relief from numbness is helped by a complex of special exercises for the hands, which includes squeezing - unclenching of fingers, bringing hands into the "lock", etc.
If the thumb of the right hand grow numb as a result of squeezing the nerve, treatment can not be delayed. The fact is that the muscle of the thumb dies with time, and a person can not already bend it, much less squeeze his hand into a fist. Specialists in this case are advised to change the occupation and minimize the time spent at the computer. Having established the diagnosis, the doctor prescribes therapy for the underlying disease, which caused the development of the syndrome, with the help of:
- ointments;
- stimulating metabolic processes of tablets;
- injections of corticosteroids ;
- physiotherapy.
In the absence of the effect of conservative treatment, an operation is performed to expand the carpal tunnel.
When osteochondrosis, the doctor prescribes medication to eliminate inflammation and swelling. In addition, the patient can be recommended therapeutic massage of the spine. With advanced osteochondrosis and hernia, surgical intervention is required.
