Carpal tunnel syndrome is a common injury involving compression of the median nerve, which runs from the forearm through the wrist and along the palm of the hand. The compression arises from narrowing of the carpal tunnel, which may be caused by thickening of the supportive tendons.
Symptoms of carpal tunnel syndrome include numbness, itching, or burning in the palm, as well as weakness or pins and needles sensations. Over time, untreated carpal tunnel can lead to muscle atrophy, causing decreased grip strength and loss of sensation.
Some individuals may be predisposed to carpal tunnel syndrome by genetic factors. Other contributing causes include overuse, trauma, and poor body mechanics.
