Quick Summary

Tenosynovitis is the inflammation of a tendon sheath. Tendon sheaths are thin tissues that allow tendons to move smoothly. When these sheaths become inflamed, often due to overuse or abnormal use of the tendons, it can cause pain, swelling, and stiffness. In some cases, bacterial infection can also lead to this condition.12

This condition can be an occupational hazard for individuals whose jobs involve repetitive motions, such as typists, baseball pitchers, or operators of pneumatic drills. Treatment typically involves resting the affected tendon and sheath, often with splints or bandages. Anti-inflammatory medications or corticosteroid injections may also be used to reduce inflammation.2
