What is Carpal Tunnel Syndrome?
Carpal tunnel syndrome is the inflammation or entrapment of nerves within the carpal tunnel of the wrist, which can cause pain and numbness. The carpal tunnel contains the median nerve and a number of muscle tendons. The nerve controls both feeling and control of your thumb and all of your fingers except for your little finger. The pain of carpal tunnel syndrome is caused by pressure on the median nerve, sometimes by fluid buildup or other conditions that can cause the carpal tunnel to decrease in size, such as swelling.
