Some runners are familiar with the painful condition called Achilles tendonitis. It occurs when the tendon that attaches your calf muscle to your heel bone becomes inflamed. Non-insertional Achilles tendonitis is the most common type to affect runners. This is a painful, degenerative condition when symptoms of arthritis are exacerbated by ongoing activity, such as athletics.
Signs of Achilles tendonitis include
- tightness in one or both calf muscles,
- pain, tenderness, swelling or unusual warmth on the back of the heel,
- Limited ability to flex your foot and ankle without discomfort
