The Achilles tendon is the tendon that connects the calf muscle to the calcaneus bone. The calcaneus is also known as the heel bone. Running, jumping, or excessive exercise may cause injury to the tendon and this can cause it to swell up.



Here is a list of common causes of achilles tendon injury:

  • Running incorrectly
  • Excessively physical activity
  • Not warming up sufficiently
  • Wearing shoes that are worn or ill-fitting shoes


  • Swelling at the back of the heel or a feeling of a sac like swelling on the achilles tendon
  • Pain or tightness with walking
  • Reduced movement of the joint or foot
  • Calf tightness or points of soreness in some people


It can be diagnosed with clinical examination. Imaging like X-ray, MRI, and ultrasounds can be useful.


  • RICE is the mainstay of treatment
  • Rest till the symptoms reduce can be very useful
  • Changing shoes every 400 to 600 km
  • Not using shoes once they are older than 6 months can help
  • Stretching and massaging the calves to reduce tightness can help
  • Wearing a shoe that helps raise the heel and reduce achilles strain can help as well.

Advanced cases of tendonitis may require surgery. Surgery may not always be ideal, however, as there is a chance of recurrence.
