Feedback wanted on reoccurring calf issue

I've had trouble with this from time to time (2010, 2020, 2022). Each time it's ended up going away eventually, but not because of anything in particular that I did beyond resting and waiting. I also found that I had to come back from the injury extremely gradually and carefully -- more so than for any other type of injury I've ever had. Good luck!

Wanted to repost here as I think I'm through the worst of this injury and perhaps it shows up in other peoples' searches. I entered physical therapy for my calf issue, which my PT diagnosed primarily as a strength and stability issue. I had once weekly sessions for ~2 months in which I would first stretch (entire leg), then massage (calf only), then strengthen (primarily calves - exercises such as weighted lunges on toes, seated calf raises, single leg calf raises). I left each session feeling fantastic, loose and with more mobility and less pain in my calf, but I'd return a week later with the same stiffness and sensitivity. I was gaining strength but not healing, which eliminated the possibility of the primary issue being strength.
I left PT and read up more on the dreaded "calf heart attack" mentioned on so many message boards and articles and began rehabilitating based on feedback from prior sufferers. Specifically, I added ~1000mg magnesium daily, began stretching the calf daily for at least 10 minutes on a 45 degree board, and foam rolled daily with a spiky foam roller (the most painful one). I also bought a muscle scraper which various PTs had used on me for prior issues.
By a wide margin the most important piece of my rehab was the foam rolling and scraping. The foam rolling was initially unbearable as I mention above. I would apply pressure specifically to the injured area for minutes at a time (to the point of tears) and my calves would be dark red (bruised) the next day. The scraper also helped (~10 minutes per leg at night). Overall this self PT routine only took 1-2 weeks and I wish I had drummed it up far sooner. The stretching and strengthening I think did very little compared to the concerted effort to break up the scar tissue.
There's still time for re-injury but for the first time in ~4 years I have no persistent stiffness or pain in the calves and I ran foam roll and massage them without pain. It is glorious.
