What is carpal tunnel syndrome?
This disease occurs when the median nerve (a major nerve which runs through the forearm branching into the palm of the hand) gets squeezed or pressed at the wrist. This nerve is responsible for controlling sensations to the palm and generating impulses to other small muscles running in the hand enabling thumb and fingers to move. This may result in pain or numbness in the wrist and eventually in the entire hand.
Signs indicating frequent burning, itching or numbness in the palm are usually the symptoms of carpal tunnel syndrome. Some patients reported that their fingers feel swollen and useless with little or no apparent swelling.
A suffering person sometimes wakes up feeling the need to shake out the wrist while sleeping at night.
As symptoms increase, people feel tingling during the day as well. In chronic cases, the muscles of the thumb may stop working permanently. Some patients reported the loss of ability to distinguish between hot and cold touch.
