Carpal Tunnel Syndrome is a very common condition in which one of the large nerves entering the hand through the wrist is compressed. Although there is debate over what causes the condition, its presenting symptoms are characteristic with mild pain or aching in the wrist associated with numbness or tingling in the thumb, index and long finger of the hand. Many patients with wrist pain are misdiagnosed as having carpal tunnel syndrome. Formal diagnosis involves obtaining an electro-diagnostic test (Nerve Conduction Study) that measures the speed that nerve impulses are conducted through the nerve. If it is compressed, the velocity with which signals are carried through the nerve will decrease proportionately with the severity of the compression. Treatment is largely based on the electro-diagnostic tests. Mild compression is treated with anti-inflammatory medication and splinting while moderate to severe compression are treated with a carpal tunnel release.
