What is Carpal Tunnel Syndrome

Carpal Tunnel Syndrome

Don't we wonder why working for long hours on computer give us numb or painful wrists. Same thing happens when we play video games for a long time. The reason our wrists undergo severe pain, numbness or a tingling sensation at times is due to a certain condition called Carpal Tunnel Syndrome. Carpal Tunnel Syndrome, commonly called CTS is a condition which occurs when the tunnel of bones and wrist's ligaments become narrow. This narrowed tunnel is responsible for the tingling sensation or numbness in our hand, as the narrowed tunnel pinches the nerve. This numbness and tingling sensation caused by the carpal tunnel syndrome can be felt on an individual's hand, especially around the thumb and first three fingers.

What Causes Carpal Tunnel Syndrome

The tunnel that gets affected due to the carpal tunnel syndrome is located under the skin of our wrist and is known as the carpal tunnel. The bottom and insides of the tunnel are formed by the wrist bones. The top of the carpal tunnel is covered with ligament. Nine tendons, that join a muscle with some other part of the body, and one median nerve passes through this carpal tunnel from our forearm to the hand. These tendons connect muscles to our bones  and thus help our hand to efficient maneuvering of the fingers and thumb. The median nerve passes through the tunnel and reaches the hand. There is very little space for the nine tendons and the median nerve to pass through. Repetitive movement such as typing or continuous movement of the wrist may result in swelling of wrist. This swelling pinches the nerve resulting in numbness or tingling sensation. One may even experience severe pain. This is the Carpal Tunnel Syndrome. Thus the symptoms of carpal tunnel syndrome include numbness, severe pain and tingling sensation in your wrist.
