What is Carpal Tunnel Syndrome?


Carpal tunnel syndrome occurs when the median nerve in the wrist is squeezed. This nerve is present in the carpal tunnel located in the wrist. When this tunnel shrinks, the nerve is compressed, causing inflammation. This results in tingling, numbness, hand pain and weakness. After lower back pain, carpal tunnel syndrome is one of the common work-related injuries. Women are more at risk. Carpal tunnel syndrome is more common in elders above 50 years.

Treatment of Carpal Tunnel Syndrome
First, the underlying cause such as arthritis or diabetes should be treated. Your physician may ask you to rest your wrist and hand, using a splint or brace. This will help ease the pressure on the median nerve.

Vitamin B6 (pyridoxine) is used to relieve some carpal tunnel syndrome symptoms. To treat the pain, doctors may recommend acetylsalicylic acid, naproxen, ibuprofen or acetaminophen. Corticosteroids may also be injected inside the carpal tunnel to relieve pain and swelling. Heat and cold application can also be effective. Severe cases of carpal tunnel syndrome need surgery.
