Tunnel Syndrome is a condition that affects the median nerve, which runs from the forearm into the hand. It occurs when there is pressure or compression on this nerve, causing pain and numbness in the affected hand. This can be caused by various factors such as repetitive motions, injury to the wrist, or prolonged use of certain tools that require gripping. The symptoms may include tingling sensations, weakness, and difficulty with fine motor skills. Treatment for Tunnel Syndrome typically involves rest, medication, physical therapy, or in some cases surgery to relieve the pressure on the nerve.
