Carpal tunnel syndrome is a condition involving the median nerve. It occurs when the median nerve becomes compressed. Compression of the median nerve in the wrist can develop into carpal tunnel syndrome, causing symptoms including numbness, tingling, burning, pain, and limited mobility in the wrist, hand, and fingers. It can be described by dull and aching sensations as well as sharp and sudden pain. Carpal tunnel syndrome symptoms can be felt in the palm as well as the wrist, thumb, pointer, middle, and ring fingers.
