The term “carpal tunnel” can strike fear in even the bravest of hearts. It causes constant pain that becomes debilitating and overwhelming.
But just what is it and what causes its symptoms? Keep reading to find out.
What Is Carpal Tunnel Syndrome?
Your median nerve runs from your palm to forearm. This main nerve controls sensation for your palm, thumb, and fingers, excluding your pinky. Impulses that move the fingers and thumb also come from the median nerve, so its function is imperative for normal hand movement.
The carpal tunnel is a small passageway at the base of the hand. The median nerve runs through this narrow pathway. When tendons in the wrist become irritated or swollen, the carpal tunnel narrows, compressing the median nerve, and resulting in Carpal Tunnel Syndrome.
