What is Carpal Tunnel Syndrome?
From National Institutes of Health  

Carpal tunnel syndrome is a painful progressive condition caused by compression of a key nerve in the wrist.   It occurs when the median nerve, which runs from the forearm into the hand, becomes pressed or squeezed at the wrist.  Symptoms usually start gradually, with  pain, weakness, or numbness in the hand and wrist, radiating up the arm.  As symptoms worsen, people might feel tingling during the day, and decreased grip strength may make it difficult to form a fist, grasp small objects, or perform other manual tasks.  In some cases no direct cause of the syndrome can be identified.   Most likely the disorder is due to a congenital predisposition - the carpal tunnel is simply smaller in some people than in others.  However, the risk of developing carpal tunnel syndrome is especially common in those performing assembly line work.
