Information for Patients


Carpal Tunnel Syndrome

You're working at your desk, trying to ignore the tingling or numbness you've had for some time in your hand and wrist. Suddenly, a sharp, piercing pain shoots through the wrist and up your arm. Just a passing cramp? It could be carpal tunnel syndrome.

The carpal tunnel is a narrow passageway of ligament and bones at the base of your hand. It contains nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the nerve to be compressed. Symptoms usually start gradually. As they worsen, grasping objects can become difficult.

Often, the cause is having a smaller carpal tunnel than other people do. Other causes include performing assembly line work, wrist injury, or swelling due to certain diseases, such as rheumatoid arthritis. Women are three times more likely to have carpal tunnel syndrome than men.

Early diagnosis and treatment are important to prevent permanent nerve damage. Your doctor diagnoses carpal tunnel syndrome with a physical exam and special nerve tests. Treatment includes resting your hand, splints, pain and anti-inflammatory medicines, and sometimes surgery.
