Has anyone had difficulty with tendonitis? I developed peroneal ankle tendonitis just after bilateral pulmonary embolisms. My activity level was very limited with balance my PT goals. I have had a hip fracture and replacement on the opposite leg and now I am developing groin and knee pain on the leg with the tendonitis. I have been in a walking boot for a month with no improvement, in fact it seems to be getting worse. Anyone have any experience with this situation or suggestions?
