The pain associated with Achilles tendinitis typically begins as a mild ache in the back of the leg or above the heel after running or other sports activity. Episodes of more severe pain may occur after prolonged running, stair climbing or sprinting.
You might also experience tenderness or stiffness, especially in the morning, which usually improves with mild activity.
If you experience persistent pain around the Achilles tendon, call your doctor. Seek immediate medical attention if the pain or disability is severe. You may have a torn (ruptured) Achilles tendon.
