Identifying achilles tendonitis

Symptoms of achilles tendonitis

Some runners are familiar with the painful condition called Achilles tendonitis. It occurs when the tendon that attaches your calf muscle to your heel bone becomes inflamed. Non-insertional Achilles tendonitis is the most common type to affect runners. This is a painful, degenerative condition when symptoms of arthritis are exacerbated by ongoing activity, such as athletics.


Signs of Achilles tendonitis include

  • tightness in one or both calf muscles,
  • pain, tenderness, swelling or unusual warmth on the back of the heel,
  • Limited ability to flex your foot and ankle without discomfort

Causes of achilles tendonitis

Achilles tendonitis is relatively common in active people, particularly walkers, runners and those who play sports that require sudden stops or directional changes. This is due to the strain that these activities can place on calf muscles. Exercising suddenly after an extended period of inactivity or starting an intense workout without warming up can also inflame the area. Other causes of Achilles tendonitis include wearing high heeled shoes for prolonged lengths of time, wearing ill-fitting or unsupportive shoes, and having pre-existing bone spurs on the heel.

How to treat achilles tendonitis

Achilles tendonitis can vary in intensity. If the pain is noticed early, the symptoms can be treated with rest, ice, compression, and elevation. This, combined with a break from exercise, may be enough to resolve the issue. Other suggestions include wearing a specialist boot or orthotic insoles to reduce pressure on the tendon, as well as attending physiotherapist sessions.

If it is continually inflamed through further exercise or there are no signs of improvement, steroid injections or even surgery may be suggested by a healthcare professional. These treatment options are usually only required if the injury isn’t addressed in its initial stages.
