How does carpal tunnel syndrome affect the body?

Carpal tunnel syndrome is the result of a compressed median nerve. This means that for one of a variety of reasons, something puts pressure on the nerve that runs down the palm side of the wrist. The median nerve is connected to the first three fingers on each hand, so when it's compressed, nerve signals to those fingers are damaged. This results in a tingling sensation or numbness that can eventually cause the muscles in the wrists and hands to weaken. If it's untreated, the nerve and muscle damage may be permanent.
