tunnel syndrome results from compression (pinching) of the median nerve. The
compression can be caused by swelling of tissue around or in the tunnel or by
bands of fibrous tissue that form on the palm side of the wrist.
symptoms of carpal tunnel syndrome are odd sensations, numbness, tingling, and
pain in the first three fingers and half of the fourth finger on the thumb side
of the hand. Sometimes the entire hand may be affected. Occasionally, there is
also pain and a burning or tingling sensation in the forearm. Burning or aching
pain with numbness and tingling often wake people at night because of the way
the hand is positioned. The person may shake the hand to try to restore normal
feeling. With time, the muscles in the hand on the thumb side can weaken and
shrink through lack of use (atrophy).
