Carpal tunnel syndrome is caused by compression of the median nerve at the wrist. This is in the center of the wrist on the palm side. Sometimes light pressure on this area will cause tingling in the fingers (Tinel sign).
The symptoms of carpal tunnel syndrome are numbness, tingling, pain, and weakness. The fingertips of the thumb, index finger and middle finger are often affected. Grip strength and movement of the thumb can be affected by carpal tunnel syndrome. The symptoms of this condition are often worse in the morning or after driving a car.
Treatment for carpal tunnel syndrome is successful with:
Wrist splinting at night time or full time
Changing keyboards (to ergonomic keyboards)
Surgery (such as carpal tunnel release)
