Carpal Tunnel Syndrome occurs when the median nerve, which runs from the forearm into the hand, becomes pressed or squeezed at the wrist. The Carpal Tunnel - a narrow, rigid passageway of ligament and bones at the base of the hand houses the median nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the median nerve to be compressed. The result may be pain, weakness, or numbness in the hand and wrist, radiating up the arm. Although painful sensations may indicate other conditions, Carpal Tunnel Syndrome is the most common and widely known of the entrapment neuropathies in which the body's peripheral nerves are compressed or traumatized.
Carpal Tunnel Syndrome Symptoms usually start gradually, with frequent burning, tingling, or itching numbness in the palm of the hand and the fingers, especially the thumb and the index and middle fingers. Some Carpal Tunnel sufferers say their fingers feel useless and swollen, even though little or no swelling is apparent. The Carpal Tunnel Syndrome Symptoms often first appear in one or both hands during the night, since many people sleep with flexed wrists. A person with Carpal Tunnel Syndrome may wake up feeling the need to "shake out" the hand or wrist. As Carpal Tunnel Syndrome Symptoms worsen, people might feel tingling during the day. |
