In Greek mythology, Achilles was a Greek hero of the Trojan War. According to legend, his entire body was invulnerable, except for his heel. Today, the large tendon on the back of the heel is known as the Achilles tendon, after this Greek hero. Due to the amount of stress and strain that we place on this part of the body, it is susceptible to injury during many athletic activities. Achilles tendonitis is a painful condition that occurs when there is damage to the Achilles tendon.

Achilles tendonitis is an overuse injury, meaning that repetitive use of this tendon results in little tears of the tissue. Over time, swelling and pain result. Common activities/conditions that result in Achilles tendonitis include:

  • Running
  • Jumping
  • Tight Calf Muscles
  • Excessively Flat Feet
The symptoms of Achilles tendonitis usually progress gradually over time. You may initially experience them first thing in the morning, or during times of increased activity. Common symptoms of Achilles tendonitis include:
  • Pain in the back of the heel when pushing off your foot during walking or standing on your toes
  • Tenderness over the back of your heel
  • Stiffness that improves as your tendon warms up
  • A "bump" on the back of your heel
  • A crackling sound when you move your Achilles tendon
While it may not always be possible to prevent developing Achilles tendonitis, taking steps to reduce your risk is important. Some preventative measures include: Management of this condition includes: medications to decrease pain and swelling, rest, and physical therapy for appropriate rehabilitation.
