What is tenosynovitis?

Tenosynovitis is a medical condition characterized by the inflammation of the synovium, a thin membrane that lines the tendons and the sheaths that surround them. It often results in pain, swelling, and tenderness along the affected tendon. Tenosynovitis can occur in various parts of the body, including the wrists, elbows, ankles, and feet. It is commonly associated with repetitive motions, overuse injuries, or underlying medical conditions.
