Carpal tunnel syndrome is a condition that causes numbness, tingling and other symptoms in the hand and arm. Carpal tunnel syndrome is caused by a compressed nerve in the carpal tunnel, a narrow passageway on the palm side of your wrist.
The anatomy of your wrist, health problems and possibly repetitive hand motions can contribute to carpal tunnel syndrome.
Proper treatment usually relieves the tingling and numbness and restores wrist and hand function.
