Carpal tunnel syndrome is a common source of hand numbness and pain. It is more common in women than men and affects up to 10 percent of the population. It is caused by increased pressure on a nerve entering the hand through the confined space of the carpal tunnel.
The median nerve travels from the forearm into your hand through a tunnel in your wrist. The bottom and sides of this tunnel are formed by wrist bones and the top of the tunnel is covered by a strong band of connective tissue called a ligament. Your doctor may make the diagnosis by discussing your symptoms and examining you. If symptoms continue to bother you, electrical testing of the nerve function is often performed to help confirm the diagnosis and clarify the best treatment option in your case.« Back to Glossary Index
