How is Achilles tendinitis diagnosed?

If you think you have Achilles tendinitis, make an appointment to see your doctor. The doctor will ask you about your recent activity and look for signs, such as:

  • The foot not flexing when the calf muscle is pressed (if the Achilles ruptures)
  • Swelling on the back of the heel
  • Pain in the back of the heel
  • Limited range of motion in the ankle

An ultrasound or MRI scan can check for tendinitis. If the tendon is enlarged, this can often be seen on radiographs (images).

How is an Achilles tendon rupture diagnosed?

The doctor will look at your foot, ankle, and leg. Often, the physical exam alone is enough to diagnose an Achilles tendon rupture. An ultrasound or a MRI may be used to determine the severity of the tear and the extent of separation of the fibers.
