Carpal tunnel syndrome is a common condition that causes pain, numbness, and
weakness in the hands and wrist. It occurs when there is increased pressure on a nerve called the
median nerve. This nerve provides sensation to the thumb, index and middle fingers, and to half
of the ring finger. The small finger, pinky, is typically not affected. The median nerve also
provides strength to some of the muscles at the base of the thumb. The carpal tunnel is a narrow
canal in the wrist. The bottom and sides of the tunnel are formed by a semi-circle of bones called
carpal bones. A strong tissue, called a ligament, forms the top of the tunnel. The median nerve
and tendons pass through this narrow space. Tendons allow the fingers and thumb to bend and
straighten. Conditions that further narrow the carpal tunnel or cause the tendons that pass
through this tunnel to swell cause carpal tunnel syndrome by compressing the median nerve.
Symptoms usually begin slowly and can occur at any time. Early symptoms include
numbness at night, tingling, and/or pain in the fingers. In fact, because some people sleep with
their wrists curled, nighttime symptoms are common and can awake people from sleep. These
nighttime symptoms are often the first reported symptoms. Shaking the hands helps relieve
symptoms in the early stage of the condition. Common daytime symptoms are tingling and
decreased feeling in the fingertips. Patients also report difficulty handling small objects, grasping
a steering wheel to drive, holding a book to read, writing, and using a computer keyboard. As
carpal tunnel syndrome worsens, symptoms become more constant. Weakness in the hand,
inability to perform tasks that require delicate motions, and dropping objects begin to occur. In
the most severe condition, the muscles at the base of the thumb visibly shrink in size.
Carpal tunnel syndrome tends to come on slowly and get worse with time. But if you treat it
early on, you can slow it down or stop it in its tracks. Early treatment can also make for a shorter
recovery time. Typically, you start with basic remedies, like wrist braces. An occupational or
physical therapist can help in a couple of ways. They may give you exercises to stretch and
strengthen your hand and wrist muscles. They can also show you how to change your routine
motions in a way that eases stress on your hands and wrists. That can be especially helpful when it
comes to tasks related to work or your favorite hobbies.
