Tendonitis in the thigh

An inflammation of a tendon is a reaction to (micro)tears in that tendon. Tendonitis in the forearm is a condition in which one or more tendons in the forearm become irritated and painful.

The tendon forms the transition between the muscle and the bone. Recovery from a tendonitis is somewhat delayed because tendons contain relatively few blood vessels compared to muscles and therefore can take up only a limited amount of healing substances.

How does a tendonitis in the forearm develop?

A tendonitis in the forearm is often caused by overuse of the wrist, hand, or fingers. The overuse can result from both repetitive movements and (too) heavy lifting.

Occupations in which such symptoms occur relatively often include computer work, working at a checkout, and knitting or sewing. Sports activities with a higher risk of forearm tendonitis include bowling, tennis, and weightlifting.

In addition to overuse, (long-term) underuse of the forearm muscles is also a risk factor. This leads to a reduced overall load tolerance of the forearm muscles and thus increases the chance of overuse.

What are the characteristics (symptoms) of a tendonitis in the forearm?

One of the most characteristic symptoms of a tendonitis in the forearm is (pressure) pain at the level of the inflamed tendon. This pain is sharp in nature and can radiate further along the tendon. Local redness or swelling can also be visible. There may be loss of strength and the arm may be less usable.

How is a tendonitis in the forearm diagnosed?

The diagnosis of forearm tendonitis can possibly already be made during the interview and physical examination by a physical therapist or family doctor. Where necessary, the physical examination is expanded with specific tests.

In case of doubt, the family doctor may choose to request additional testing. With imaging, mainly ultrasound, the precise location and severity of the problem can be visualized.

What does the treatment of a tendonitis in the forearm look like?

In the first phase of treatment, the focus will be on pain management (reducing pain). Dosed rest and cooling of the painful tendon play an important role. If necessary, the family doctor will prescribe anti-inflammatories. Such medicines are aimed at reducing the signs of inflammation.

When the pain and other signs of inflammation subside, treatment will focus more on functional recovery and increasing load tolerance. It is recommended to follow this treatment path under the guidance of a physical therapist. Common treatment interventions include exercise therapy, massage, taping, stretches, and joint mobilizations.
