Carpal tunnel involves the pinching or impingement of the nerves that supply the hand, specifically the thumb, pointer, and part of the middle finger. This can often result in a sensation of pain, tingling (pins and needles), burning, or even hand weakness in severe cases. In cases of true carpal tunnel the nerve impingement will occur at the level of the wrist, but the impingement of the same nerves can occur in several locations above the wrist in the forearm, elbow, shoulder, and even the neck. For those who suffer with carpal tunnel or a different impingement of the nerves of the hand, it can be very debilitating.
