A lump on the back of the heel bone
You may notice a hard spot or thickening at the back of your heel. Shoes with a firm heel counter, in particular, can feel uncomfortable or cause pressure. Sometimes the area becomes tender, red or painful when walking or exercising.
Many people find that certain shoes are less comfortable or that they start to avoid wearing shoes because of the pressure on the heel.

What is it?
A lump at the back of the heel bone is often a bony protrusion. This is also known as Haglund’s exostosis. The bony protrusion is usually located close to the attachment of the Achilles tendon.
The lump itself does not always have to be painful. Symptoms mainly occur when a shoe presses on it or when the bursa or Achilles tendon becomes irritated.
Causes
A lump on the back of the heel is often caused by prolonged pressure or friction on the heel. This can cause the area to become increasingly sensitive or swollen.
Possible causes are:
- constitution or foot shape;
- shoes with a hard heel edge;
- a flat foot or high instep;
- doing a lot of sport or walking;
- stiff calf muscles;
- Achilles tendon complaints;
- an abnormal gait pattern;
- prolonged pressure on the back of the heel.
What do you notice?

The impact of a healthy lifestyle and your mental health
Getting enough exercise is important, but it is also important to minimise pressure on the back of the heel.
Gradually building up your walking or exercise routine and allowing sufficient time for recovery can help to reduce heel pain. Wearing good shoes that put less pressure on the sensitive area is important in this regard.
Sleep, diet and a healthy body weight can also contribute to better recovery and reduce strain on the feet. Pain or pressure in shoes can be frustrating and affect how much you move around.
Our lifestyle coaches can support you with changes relating to sleep, diet and weight that are suited to your situation.
What can you do yourself?

- choose shoes with enough room around the heel;
- temporarily adjust the sports tax;
