Does pressure on your median nerve cause carpal tunnel syndrome?

ANSWER

Carpal tunnel syndrome is caused by pressure on your median nerve. This nerve gives you feeling in your thumb and all your fingers except your pinky. When it goes through your wrist, it passes through the carpal tunnel -- a narrow path that’s made of bone and ligament. If you get any swelling in your wrist, this tunnel gets squeezed and pinches your median nerve, which causes your symptoms.
