Carpal Tunnel Syndrome

Carpal tunnel syndrome is a common source of hand numbness and pain. The syndrome is commonly described as a tingling sensation.

Carpal tunnel syndrome occurs when the tissues surrounding the flexor tendons in the wrist swell and put pressure on the median nerve. These tissues are called the synovium. The synovium lubricates the tendons and makes it easier to move the fingers.

This swelling of the synovium narrows the confined space of the carpal tunnel, and over time, crowds the nerve. Carpal tunnel syndrome is caused by pressure on the median nerve traveling through the carpal tunnel.
