A tendon is a kind of fibrous tissue that connects the body’s muscles to the bones. A protective sheath called the synovium covers the tendons and produces synovial fluid that keeps the tendon lubricated.

Injury to the tendon can result in malfunction of the sheath. The inflammation or swelling of the sheath is known as tendon sheath inflammation or tenosynovitis.

This blog is a comprehensive guide to tenosynovitis, its symptoms, causes, and treatment methods.
