Carpal Tunnel Syndrome symptoms
Carpal tunnel syndrome (CTS) is a relatively common condition that causes pain, numbness and a burning or tingling sensation in the hand and fingers. Symptoms of CTS can range from mild to severe.
The carpal tunnel is a small tunnel that runs from the bottom of the wrist to the lower palm.
Several tendons that help to move the fingers pass through the carpal tunnel. So does the median nerve, which controls sensation and movement of your hand.
On the inner side of the wrist the carpal tunnel is enclosed within tissue called the transverse carpal ligament.
In cases of CTS, the space inside the tunnel is made smaller by the increased tissue pressure and a build-up of fluid in the tissue (oedema). This places pressure on the median nerve. The pressure is increased further when the wrist and fingers are bent (flexion). Compression of the median nerve causes the symptoms of pain and numbness.
