These Are the Four Types of Foot Tendinitis
Posted on Mar 08, 2021

Tendonitis commonly presents in the feet in four different areas:

  • Achilles Tendonitis
  • Peroneal Tendonitis
  • Posterior Tibial Tendonitis
  • and Extensor Tendonitis.

Today, we’re helping you learn the differences and how you can find relief from tendonitis pain.


To summarize –

Damage or overuse can irritate and inflame a tendon, or the fibrous tissue that links your bones and muscles together.

This pain is called usually called tendonitis and can strike anywhere in the body where tendons are located.

Tendonitis is often accompanied by swelling and tightness, and if left untreated can even lead to mobility issues.


Tendonitis in the feet can make walking, standing, and exercising painful. Let’s look at the four major forms of tendonitis that can affect the feet.

Achilles Tendonitis

This form of tendonitis affects the back of the leg and the heel where the Achilles tendon is located.

This tendon connects your heel bone and calf muscles. Pain can flare up after long periods of physical activity.

Damage to the tendon can occur after periods of immobilization too - this often happens after casts or boots are used for other conditions.  

Achilles tendonitis is most often developed through repetitive strain, commonly through sports or exercise-related injury.

In actuality, nobody really knows why or how many people suffer from this condition. Again, it is random.

However, scientists and surgeons do know that it is very painful!

Peroneal Tendonitis

Sufferers of peroneal tendonitis feel pain experience pain and swelling in their ankle that is especially sensitive after periods of rest.

Like Achilles tendinitis, this form of tendinitis is felt in the ankle, specifically on the outside of the foot and leg.

The repetitive motion of running can influence the development of peroneal tendInitis and will also exacerbate an existing case.

The peroneal tendons are involved in balance during almost all upright activities.

As such, these are constantly on the move.

It is very common for people without pain to have tears of these tendons on MRI due to the heavy daily use.

However, a painful peroneal tendon is likely irritated enough to be called ‘inflamed.’ This is tendonitis.

Posterior Tibial Tendonitis

This form of tendonitis is one of the most common causes of foot pain.

This is due to the inflammation of the posterior tibial tendon, or the connecting tendon between the calf muscles and the central bones of the foot.

The posterior tibial tendon is responsible for the highest point of the arch of the foot.

It is used all day long to initiate the act of ‘pushing-off’ during walking or running.  

This condition can be caused by injury or overuse and causes pain that runs along the inner side of the foot and ankle.

This tendon also becomes prone to damage for those with midfoot instability or flat feet.

Extensor Tendonitis

Extensor tendonitis can affect both your hands and feet at the bendable joints of your fingers, wrists, and toes. Wearing tight, irritating shoes or overuse are typical causes of extensor tendonitis.

However, these tendons are used all day to lift the foot during walking.

If you have a tight calf muscle, as most of us do, then they are fighting that calf muscle all day too - this can lead to tendonitis in and of itself!

Pain from this condition is felt on top of the foot and can cause the tendons to become weak.


If you are struggling with pain from tendonitis, don’t lose hope! You can find relief with surgeon-designed technology.

Dr. Meredith Warner is a practicing orthopedic surgeon who helps patients recover from foot pain every day.

Dr. Warner knows that the body is built to recover naturally and created The Healing Sole and Well Theory as an alternative to expensive, invasive, chemical-laden treatment.

The Healing Sole is purposefully-designed to allow the muscles, tendons, ligaments and fascia of the feet to heal naturally.

A firm rocker bottom sole protects the feet, offloads stress, and gently stretches the muscles of the feet and lower legs as you walk.

This is paired with a raised arch for support, an inner heel compression for stress relief, and a metatarsal bar to help alleviate tension at the forefoot.

A few hours of wear each day is all you need to help fight off pain!

Dr. Warner’s Well Theory products can help to fight pain and inflammation with daily supplementation or simple applications of our soothing PEA creams.

The Well Theory is another way that allows you to empower your own natural healing!
