What is Carpal Tunnel Syndrome?

Carpal Tunnel Syndrome

Quick Answer

A condition where pressure on the median nerve in the wrist causes pain, numbness, and weakness in the hand. It often results from repetitive hand movements or prolonged wrist positions.

Overview

Carpal Tunnel Syndrome 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 tingling, numbness, and weakness in the fingers and hand. It is often caused by repetitive motions, such as typing or using a mouse, which can irritate the surrounding tissues and increase pressure in the carpal tunnel. The carpal tunnel is a narrow passageway in the wrist that houses the median nerve and tendons that bend the fingers. When the tunnel becomes narrowed or swollen, it puts pressure on the median nerve, leading to discomfort and potentially affecting daily activities. For example, someone who spends hours working on a computer may start to notice these symptoms, making it difficult to perform tasks like typing or gripping objects. Understanding Carpal Tunnel Syndrome is important because it can significantly impact a person's quality of life. If left untreated, it can lead to chronic pain and permanent nerve damage. Early diagnosis and treatment can help relieve symptoms and prevent further complications, making it crucial for those experiencing signs of the condition to seek medical advice.
