Carpal tunnel syndrome is a condition caused by compression of the median nerve as it passes through the carpal tunnel, a narrow passageway in the wrist. This pressure can lead to symptoms such as numbness, tingling, burning sensations, weakness, or pain in the thumb, index, middle, and part of the ring finger. It often develops gradually and is commonly associated with repetitive hand movements, prolonged wrist flexion, pregnancy, diabetes, thyroid disorders, or inflammatory conditions. Symptoms may worsen at night or with continued use of the hands. Treatment ranges from wrist splints and activity modification to anti-inflammatory medications, corticosteroid injections, or surgical release in more severe or persistent cases.
