Carpal tunnel syndrome
An MSD that results when tendinitis or any other swelling in the wrist puts pressure on the median nerve as it passes through the carpal tunnel. The carpal tunnel is a small opening in the wrist through which the median nerve and nine tendons that connect the muscles in your arm to the bones of your hand pass. Early symptoms of carpal tunnel syndrome include a tingling or a numb sensation in any of the first three fingers or the thumb.
