What is Carpal Tunnel Syndrome?

Carpal tunnel syndrome

Carpal tunnel syndrome is caused by compression of the median nerve that controls sensation and movement in the hands.  It causes numbness, tingling and pain in the thumb, index and middle finger that often worsens at night. This condition can affect one, or both hands and it is sometimes accompanied by weakness in the thumb.

It is a painful, progressive, condition caused by compression of the median nerve (which runs from the forearm into the hand) in the wrist. It results from pressure on this nerve where it passes from the wrist into the hand, through the carpal tunnel.

As the median nerve carries the sensory messages from the thumb, index and middle finger, as well as the motor stimuli to the muscles of the hand, any damage to it causes sensory disturbances, in particular the numbness, tingling and weakness.

Carpal tunnel syndrome usually starts gradually, with pain, weakness, or numbness in the hand and wrist, radiating up the arm.
