Achilles tendinosis advice needed
Seeking advice getting out of my Achilles tendinosis/tendinopathy (not tendonitis) trap.
To explain further, I had a bad foot injury which took 4 months to heal, and I lost a lot of condition in my foot over that period. I then had to battle through tendinosis in my posterior tibialis and FHL tendons as I built the strength back up. The solution I found was to very gradually build up strength by using static or foot-weight only exercises and then really weak (homemade) elastic bands. If I went too hard (as one would normally do with muscle building), it would just micro-tear / exacerbate and I'd have to rest it for a couple of days before starting again. This did work and I have no problems with those tendons now.
However, when I was trying this approach with the Achilles/calf, using sitting down heel raises, it's been less than straight-forward. I first tried doing 6 reps of full range of motion heel lifts, but that just exacerbated it. Then tried 1 full rep (after a couple of days of rest) and then 1 shortened range rep and that still didn't work.
The really annoying thing is that I hadn't even injured my Achilles/calf initially, but during the healing period for my foot, my SEM consultant told me to aggressively (statically) stretch my calves to aid healing, and that I shouldn't worry about overstretching it as it won't do any harm. Turns out I have a high pain threshold, and I definitely did f**k it up by over stretching it, before then falling into the tendinopathy trap as it healed. It was only after this that I discovered dynamic stretching off t'internet, which works much better for me.
Has anyone gone through this themselves, or know of a really gentle way to strengthen the Achilles/calf?
Edit: Just to clarify, I have seen a physio a couple of times, who's a foot specialist and pretty good, but she's a bit of a drive away and I've had some other health issues which has got in the way so thought I would tap into the hive mind here.
