Carpal tunnel syndrome

MedlinePlus says carpal tunnel syndrome is the name for a group of problems that includes numbness, tingling, weakness or pain in your wrist or hand. It happens when a nerve in your wrist becomes squeezed. The nerve involved is the median nerve, which runs through the carpal tunnel. This site does not state that a TENS unit treats carpal tunnel syndrome. Ask your clinician before you try TENS for hand or wrist pain, and follow your clinician's and your device's instructions.
