The Carpal Tunnel is a tight, narrow, C-shaped passageway in the wrist that is made up of tiny bones and ligaments. Some of the tendons and nerves that control movement of the fingers has through the carpal tunnel into the hand. These tendons are covered with a fluid filled sheath. It helps them glide smoothly during movement. During repetitive hand motions like typing, the tendons become irritate causing swelling and inflammation within the sheath. Because the carpal tunnel is made up of bones and ligaments, it cannot expand to accommodate the swelling, this causes the nerves of the hand to become pinched or compressed, resulting in pain or numbness in the fingers.
