Carpal tunnel syndrome, or CTS, is a disorder of the wrist and hand. It causes numbness and tingling that may affect sleep. It can also cause pain and a weakened grip. Generally symptoms begin during the night, but if left untreated, they can intrude on daytime activities. They may worsen over time.
CTS is caused by crowding in the carpal tunnel, an important part of the structure of the wrist. The carpal tunnel is home to the median nerve, which is an important nerve that serves as the link between the hand and the brain. The carpal tunnel also contains the flexor tendons, which slide against each other as the fingers move. In order to slide easily, these tendons are covered in a protective outer sheath. Generally, this sheath is thin enough to allow plenty of space in the carpal tunnel. However, the sheath can sometimes become thickened, which crowds the space inside the carpal tunnel. The result is CTS.
If you suspect you may have CTS, your doctor will ask you to describe your symptoms. X-rays will be taken to rule out broken bones or arthritis. You may also have to have a nerve conduction test or an EMG. CTS can be treated with medications, injections of cortisone, or by wearing a splint. Surgery is also an option if other treatments fail, or if your CTS symptoms are very severe.
