Why does achillies pain come and go?

Tightness: Many time the posterior leg muscles are attached to the lower femur. When the leg stretches, so does the Achilles tendon which attached the same muscles to the back of the heel. When there is too much stretching there is inflammation and pain. Rest and other treatments may make the pain go away and if the tendon is re stretched too much the pain will return. In some cases a heel left will help

Varies: There are multiple potential causes of episodic pain in the Achilles area from inflammatory causes, contracture, traumatic, and degenerative etiologies. Don’t hesitate to be seen for a specific diagnosis and treatment options.
