Carpal Tunnel Syndrome

The carpal tunnel is a narrow tunnel to the wrist (palm surface) through which the median nerve passes. Carpal tunnel syndrome occurs when the tissues surrounding the wrist flexors swell and thereby squeeze the median nerve.

These tissues are called the "synovial membrane" which lubricates the tendons so that the fingers can move more easily. This swelling of the synovial membrane narrows the area of the carpal tunnel and over time squeezes the median nerve.

The causes vary, namely hand overdose, advanced age, heredity (in some people the carpal tunnel passes the tube is smaller), and finally diseases such as diabetes, rheumatoid arthritis and diarrhea. This syndrome usually manifests itself gradually with numbness or pain in the hand, the feeling of electrical current in the index finger and middle finger (areas that affect the median nerve).
