Carpal Tunnel Syndrome is a condition in which the median nerve is compressed at the wrist. This could be due to tendon enlargement, arthritis, fractures or increased fluid in the wrist (which could be a result of pregnancy or increased weight). The symptoms are usually worse at night and may be aggravated by driving.
Surgery releases where the nerve is trapped over the carpal tunnel area in your wrist. It is a small incision on the palm of your hand. It is necessary when you are waking up several times in the night, have consistent pain and/or there is noticeable deterioration of your median nerve. This deterioration can be detected in a nerve conduction study.
