I do not have achilles tendonitis but do have peroneal tendinitis. I was pretty worried bout it as it came out of the blue. I did two sessions of physical therapy and while not ground breaking, the massage they did along with dry needling helped a lot. I am back on my bike doing all out sprints and long rides with no issues. I’m doing my exercises as well and that really does seem to help.
I also have weak ass hips.
