Carpal tunnel syndrome occurs when
the median nerve, which go from the forearm into the palm of the hand,
becomes pressed
or squeezed at the wrist. The median
nerve controls sensations to the palm side of the thumb and fingers
(although not the
little finger), as well as impulses
to some small muscles in the hand that allow the fingers and thumb to
move. The carpal
tunnel - a narrow, rigid passageway
of ligament and bones at the base of the hand - houses the median nerve
and tendons. Sometimes,
thickening from irritated tendons or
other swelling narrows the tunnel and causes the median nerve to be
compressed. The result
may be pain, weakness, or numbness
in the hand and wrist, radiating up the arm.
Carpal tunnel syndrome is common in people who perform repetitive hand and wrist. Typing on a computer keyboard is probably the most common cause of this syndrome. Other causes include:

* Work on an assembly line
* Paint
* Write
* Use tools (especially hand tools or tools that vibrate)
* Sports such as racquetball and handball
* Playing musical instruments
The condition often occurs in people 30 to 60 years and is more common in women than in men.
Many health problems are associated with carpal tunnel syndrome, including:
* Bone fractures and arthritis of the wrist
* Acromegaly
* Diabetes
* Alcoholism
* Hypothyroidism
* Renal and Dialysis
* Menopause, premenstrual syndrome (PMS) and pregnancy
* Infections
* Obesity
