Achilles tendinitis is an overuse injury of the Achilles tendon. The Achilles tendon is a thick and strong tendon that attaches the calf muscles to the back of the lower leg to your heel bone. Tendinitis refers to inflammation of the tendon, causing pain and stiffness. Achilles tendinitis commonly occurs in middle-aged people who sporadically play sports, and runners who suddenly increase the intensity or duration of their runs.

The Most Common Causes of Achilles Tendinitis
- Repetitive or intense strain on the tendon and calf muscle
