Since the median nerve provides sensations to the palm side of the thumb, index, middle and ring fingers, and supplies the muscles that are responsible for thumb movement (see Figure 1), the carpal tunnel symptoms will affect those areas. The symptoms of carpal tunnel syndrome include:
☛ Numbness or tingling in the thumb, index, middle, and half of the ring finger.
☛ Pain in the hand and wrist that can radiate to forearm and sometimes arm or neck.
☛ Weaker grip, occasional clumsiness, or a tendency to drop things.
☛ Difficulty with grasp is usually seen in severe and chronic cases, where the muscles at the base of the thumb slowly shrink (thenar atrophy).
