Side effect: Carpal tunnel is a nerve injury to the median nerve that travels through the wrist. I do not know you symptoms prior to surgery but most often there is pain or numbness in the hand. Carpal tunnel release usually will help lessen the pain but can result in numbness in the area that was originally painful. It can improve with time. Can take up to a year to heal. Discuss with your doc.
