Carpal tunnel syndrome affects the hand and arm. It is caused by a pinched nerve in the wrist and compression of the carpal tunnel, a passageway on the palm side of the wrist. Hand overuse and certain underlying problems, like inflammatory and nerve damaging conditions, can contribute to the condition.

Symptoms: The main symptoms of carpal tunnel syndrome are numbness, tingling, and weakness in the hand and wrist. The symptoms typically start gradually.

Treatments: The goal of treatment for carpal tunnel syndrome is to relieve pressure in the carpal tunnel. Wrist splinting, non-steroidal anti-inflammatory drugs, and corticosteroids can help relieve symptoms. Surgery may be needed to cut the ligament inside the carpal tunnel in order to free up the nerve. Temporary relief can be provided with rest and over-the-counter pain relievers.
