As a result, numbness occurs in the areas covered by this nerve, in the thumb, index, and middle fingers, at first only intermittently, during the day and then at night, and finally this numbness becomes permanent. Increasingly sharp pain, sensory disturbances, tactile numbness occur, and are accompanied by the weakening of the fingers and palms.
The wrist is usually swollen, pressure sensitive, and the pain increases as you move it, especially when you bend it back, often radiating to the forearm and shoulders and neck.
In the advanced state of the disease, due to the pressure on the nerve, the muscles of the palm begin to atrophy, and their grip strength weakens.
It usually develops in the more used, dominant hand.
