Symptoms & Causes of Achilles Tendonitis

Insertional Achilles Tendonitis is caused due to excessive strain on the tendon at the point where it inserts into the bone.

It causes pain and sometimes swelling at the back of the heel.

Insertional Achilles Tendonitis Symptoms

Insertional Achilles tendonitis is inflammation at the back of your heel, where your Achilles tendon inserts into your heel bone, causing tenderness and pain in the area. It may be associated with a bone spur – a bony growth on your heel bone due to the build-up of calcium deposits.

You may experience a particularly stiff tendon in the morning or if you haven’t moved around for a while, although it tends to loosen up after a while. The pain may also feel worse after longer bouts of activity.

If you’re experiencing one or more of the following symptoms, you should book an appointment with one of our consultants, who are experts in treating this condition with radiotherapy.

✔ Pain in the back of your heel
✔ Stiffness in the Achilles tendon, which runs from your calf muscle to the back of the heel
✔ Swelling at the back of your ankle
✔ Tenderness when you touch the tendon

Insertional Achilles Tendonitis Causes

There is no single cause for insertional Achilles tendonitis but there are several risk factors that are associated with an increased risk of developing it, including:

✔ A sudden increase in exercise
✔ Abnormal foot mechanics – including flat feet
✔ Activities which require you to stop or change direction quickly – such as tennis
✔ Exercising without a proper warm-up
✔ Haglund’s deformity – a foot condition where the back of the heel bone is more prominent and rubs against the Achilles tendon, causing irritation
✔ Repeated physical activity that puts a strain on your Achilles tendon
✔ Vigorous or excessive exercises
✔ Wearing poorly fitting shoes or high heels

Insertional Achilles tendonitis commonly occurs in athletes as many of the associated risk factors are related to exercise.
