Some people with CTS say their fingers feel useless and swollen, even though little or no swelling is apparent. Symptoms usually start gradually, with frequent numbness or tingling in the fingers, especially the thumb and the index and middle fingers. Top What are the symptoms of carpal tunnel syndrome? CTS is the most common and widely known of the entrapment neuropathies, in which one of the body’s peripheral nerves is pressed on or squeezed. The result may be numbness, weakness, or sometimes pain in the hand and wrist (some people may feel pain in the forearm and arm). Sometimes, thickening from the lining of irritated tendons or other swelling narrows the tunnel and compresses the median nerve. It also controls some small muscles at the base of the thumb. The median nerve provides feeling to the palm side of the thumb and to the index, middle, and part of the ring fingers (although not the little finger). The carpal tunnel-a narrow, rigid passageway of ligament and bones at the base of the hand-houses the median nerve and the tendons that bend the fingers. How can carpal tunnel syndrome be prevented?Ĭarpal tunnel syndrome (CTS) occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist.
