Carpal tunnel syndrome is caused by pressure on the median nerve. The carpal tunnel is a narrow passageway surrounded by bones and ligaments on the palm side of your hand. When the median nerve is compressed, the symptoms can include numbness, tingling and weakness in the hand and arm.
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.
