Carpal tunnel syndrome is a common condition that affects both hands and forearms. It involves the nerves, bones, and ligaments that connect the arm and the hand. This condition is caused by pressure on the median nerve. The median nerve runs the length of the arm, goes through a space in the wrist, and ends in the hand. This condition occurs when swelling puts pressure on the median nerve at the wrist.
The symptoms of carpal tunnel syndrome include pain and cramping of hands and tingling of the fingers. Often this leads to patients waking up night wanting to shake-off their hands. In more severe cases, however, it can also result in weakness of the hands. It can be to the point that people involuntarily drop objects. As carpal tunnel progresses it can also cause cramping and pain of the forearm, arms, and even the neck muscles.
