CARPAL TUNNEL SYNDROME (CTS)
Carpal
tunnel syndrome (CTS) is a painful condition caused by pressure
on the median nerve, one of three main nerves passing from the arm
to the hand. The median nerve passes through the wrist, which consists
of eight small bones that form a "tunnel". The tunnel
narrows, due to swelling of the protective sheaths around the wrist
tendons, resulting in pressure on the sensitive median nerve.
Symptoms of CTS develop gradually. The first signs are numbness
and tingling, or pain in the palm, thumb, index, middle and ring
fingers. The pain often wakes up people at night, when symptoms
can be the most severe. The pain also occurs with vigorous hand
activity. As CTS worsens, hands get weak, lose muscle control, and
can, after years without treatment, become crippled.
CTS is caused by repetitive hand, finger or wrist movements. Other
causes include hormonal factors related to menstruation or pregnancy,
thyroid disease, Lyme disease, diabetes and rheumatoid arthritis.
