Tendinitis is inflammation, irritation and swelling of a tendon, which is the tissue that joins the muscle and bone together. It can be caused by overuse, injury or aging and is seen in people with diseases such as diabetes and rheumatoid arthritis. It is most common in the elbow, heel, shoulder or wrist.

- Immobilization, usually with splint or removable brace
- Nonsteroidal anti-inflammatory medications, such as aspirin or ibuprofen
- Physical therapy to stretch and strengthen the muscle and tendon
- Though uncommon, surgery can remove the inflamed tissue around the tendon
