Carpal tunnel syndrome is a condition that occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes compressed at the wrist. This compression can lead to symptoms such as numbness, tingling, and weakness in the hand and fingers. It is often associated with repetitive hand movements, such as typing or using a mouse. The carpal tunnel is a narrow passageway in the wrist that houses the median nerve and tendons. Factors contributing to carpal tunnel syndrome include arthritis, pregnancy, and certain health conditions like diabetes. Treatment options range from wrist splints to surgery, depending on the severity of the condition.
