Carpal tunnel syndrome is where pressure on a nerve in your wrist causes pain and numbness in your hand and fingers.
Symptoms of carpal tunnel syndrome include pain, numbness, tingling or weakness in your fingers, hand or arm.
Resting your hand and supporting it with a wrist splint can help ease carpal tunnel syndrome. Some people need steroid injections or surgery.
Carpal tunnel syndrome happens when the carpal tunnel inside your wrist swells and squeezes a nerve. It can be caused by repetitive hand movements.
