What Is Tendonitis of the Foot?
Tendonitis is a common foot condition that occurs due to tendon injuries. There are different types of tendonitis and they are identifiable by which part of your feet they affect.
Achilles Tendonitis
The Achilles tendon is a large tendon that attaches the calf muscles to the back of the heel. Achilles tendonitis affects the back of the ankle and is a common sports injury that occurs when an activity level is suddenly increased, or a new activity is started.
Posterior Tibial Tendonitis
This affects the inner side of the ankle and causes strain on the tendon of the tibialis posterior muscle which is at the back of the lower leg. Posterior tibial tendonitis usually occurs due to flat feet.
Peroneal Tendonitis
In peroneal tendonitis, the tendons of the peroneal muscles which are on the outer side of the ankle cause pain and possibly swelling. High-arched feet and a history of ankle sprains could put you at risk for this type of tendonitis.
Flexor Tendonitis
This affects the inner back of the ankle especially among dancers or people who do activities that require a lot of toe balancing.
Extensor Tendonitis
This affects the top of the foot and is usually caused by your foot rubbing against your shoe.
Common Symptoms of Tendonitis
- Pain especially when you first start an activity, like getting up and walking.
- Swelling is expected.
- Symptoms worsen when affected tendon is used.
- Stiffness in foot and ankle.
- Rest relieves the pain.
Causes
- Overuse – Repetitive activity can cause a tear in the tendon.
- Abnormal Foot Structure – Flat feet or high arches.
- Trauma – Injuries and accidents.
- Medical Conditions – Like RA and gout.
Tendonitis Treatment
Your podiatrist may suggest some of the following treatments for tendonitis that include:
- RICE treatment.
- A walking boot to keep foot and ankle immobilized.
- Orthotics like arch supports, inserts, prescription braces, custom foot orthotics, etc.
- Nonsteroidal anti-inflammatory drugs.
- Physical therapy that includes stretching and strengthening exercises to help reduce the stress on the affected tendon.
