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. The Carpal tunnel is named for the area of your wrist containing thecarpal bones, the transverse carpal ligament (connecting two outside carpals together), the median nerve and the tendons controlling finger and hand movement. Pressure on the median nerve may occur due to an injury (for example, a sudden bending back of the wrist),  or sustained pressure from activities
like typing/keypunching, chopping, hammering or  pushing.
