Forearm tendonitis

Inflammation of a tendon is a reaction to (micro)tears in that tendon. A 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. The recovery of a tendonitis is somewhat delayed because tendons, relative to muscles, contain few blood vessels and can therefore absorb only limited repair substances.

How does a tendonitis in the forearm arise?

A tendonitis in the forearm is often caused by overuse of the wrist, hand or fingers. The overload can be the result of repetitive movements as well as (too) heavy lifting work.

Occupations in which such complaints occur relatively often include computer work, working at a checkout and knitting or sewing. Sports activities with a higher risk of a tendonitis in the forearm are, for example, 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 capacity of the forearm muscles and thereby increases the risk of overuse.

What are the symptoms of a tendonitis in the forearm?

One of the most characteristic symptoms of a tendonitis in the forearm is (pressure) pain at the site of the inflamed tendon. This pain is sharp and can radiate further along the tendon. Local redness or swelling may 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 a tendonitis in the forearm can possibly already be made during the consultation and physical examination by a physiotherapist or GP. Where necessary, the physical examination is supplemented with specific tests.

In case of doubt, the GP may choose to have additional tests performed. With imaging, mainly ultrasound, the exact location and severity of the symptoms can be visualised.

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

In the first phase of treatment the focus will be on pain management (pain reduction). Graded rest and icing of the painful tendon play an important role. If necessary, the GP will prescribe anti-inflammatories. These medicines are aimed at reducing the signs of inflammation.

As the pain and other inflammatory signs decrease, treatment will focus more on functional recovery and increasing load capacity. It is advisable to follow this treatment programme under the guidance of a physiotherapist. Frequently used interventions include exercise therapy, massage, taping, stretching and joint mobilisations.
