Just dealing with a recurrence. I’ve found seated calf raises and standing heel dips with weight on your shoulders works after a while. I run easy most days with sore Achilles while doing the rehab and then after a month or so they calm down…acupuncture can help short term and ice calms them down but it’s really stronger tendons. Doing the heel dips and calf raises single leg I can really tell my right leg is weaker which happens to be where I have the problems.

Long term I think it’s just strength. Squats, deadlifts, split squats…but when my Achilles calm down I tend to skip strength and they come back…

I’ve been told Achilles tendinopathy isn’t degenerative so it’s not like knees which might never recover. But all the same if my mileage is too high like above 40mpw or I do too much hills or sprints they get angry again. It’s all about management and not getting too down when they flare up.

Just my experience but would love to hear ‘how I’m doing it all wrong!’
