If you develop pain in your body that limits normal motion, you may have tenosynovitis, a condition in which a tendon and its covering (the synovial sheath) become inflamed and irritated. Tendons are your body's structures that connect muscles to bones. The inflammation of the tendon and sheath in tenosynovitis may cause pain, swelling, and limited use of the body part affected.
