There are 27 bones in each human hand, of which, 4 create The Carpal Tunnel, located in the wrist. Literally, it is a narrow tunnel or passageway that protects the main nerve going to the hand and tendons. Carpal tunnel syndrome is caused by a pinched nerve in the wrist. It begins with a pain forming in the hand and wrist. When this nerve is compressed severely enough, numbness and tingling, pain and weakness can occur in the hands and fingers. Carpal tunnel syndrome can make it difficult to accomplish simple daily tasks such as holding a coffee mug or opening jars and door knobs.
Several key triggers of carpal tunnel syndrome are poor ergonomics, overuse and repetitive motion, fluid retention during pregnancy and menopause, and injury.
