Carpal Tunnel Syndrome is a problem of the median nerve which runs from the forearm into the hand. When there is excessive pressure in the wrist, it causes swelling of the median nerve. This small area called the carpal tunnel is a narrow tunnel at the wrist made up of bones, soft tissues, nerves, tendons, ligaments and blood vessels. When the median nerve which runs through this tunnel gets compressed it causes pain, weakness, numbness or tingling in the hand and wrist which radiates into the forearm. The carpal tunnel is the most common area that gets compressed in both the hands and feet.
