Tendonitis is inflammation of a tendon. A tendon is the cord or band that connects a muscle to a bone.

What is going on in the body?

Tendons are usually smooth and strong. With age or overuse, tendons can become worn and weak, leading to tendinitis. Tendinitis occurs most often in the shoulder, elbow, wrist, hip, knee, and ankle.


What are the causes and risks of the condition?

Tendonitis is caused by overuse, injury, or aging. It can also be associated with inflammatory diseases that occur throughout the body, such as rheumatoid arthritis. Rarely, it is caused by an infection such as gonorrhea.


What can be done to prevent the condition?

Excessive repetitive motions should be avoided.


How is the condition diagnosed?

Tendinitis is usually suspected after observing the signs and symptoms. An X-ray is not often helpful. Although rarely necessary, a special X-ray test known asMRI, or magnetic resonance imaging, can reveal any weakening of the tendon or changes in the tendon sheath or covering.

Long Term Effects

What are the long-term effects of the condition?

Tendinitis may become chronic or long-term, and may lead to rupture of the tendon.

Other Risks

What are the risks to others?

There are no risks to others.


What are the treatments for the condition?

RICE (Rest, Ice, Immobilization, and Elevation) is the appropriate treatment for tendonitis. Temporary use of a splint can help rest the tendon. Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (i.e. Advil, Motrin) or naproxen (Naprosyn, Aleve, Anaprox, Naprelan) can also be taken to reduce inflammation, swelling, and discomfort.
Occasionally, it is beneficial to inject a corticosteroid, such as triamcinolone, into the tendon sheath. Physical therapy may also help and includes massage, ultrasound, and stretching and strengthening exercises. It is important to stretch before and after activity. Although rarely necessary, surgery can be useful. It can clean out the inflammatory tissue from the tendon sheath or relieve pressure on the tendon by removing bone.

Side Effects

What are the side effects of the treatments?

NSAIDs may cause indigestion, ulcers, or bleeding. They may also affect the kidneys or liver. Surgery and medication injection carry a risk of bleeding and infection.

After Treatment

What happens after treatment for the condition?

With a return to activity, tendinitis can recur. Prolonged tendinitis in certain areas of the body can lead to rupture of the tendon.


How is the condition monitored?

Pain and swelling should be monitored and reported to the healthcare professional.
