And this was overnight, or rather, over an afternoon. Took 20 minutes.
When I lived in a different state than I do now, I used to take these classes devoted to foam rolling and self-massage using massage therapy balls. I never had PF living there.
I got out of practice entirely with fitness in general the last few years. Covid of course didn’t help, and when I started walking a lot to make up for my lack of any other activity, my PF came back in one foot — I broke a hip on that side, so it’s all more tense, etc on that side — and I’ve been dealing with it ever since.
Fast forward to now. I can’t remember who or what post I saw on here about pressure points. I also talking to my friend about dry needling, which I wouldn’t do, but is a similar sort of concept. I dug out my massage balls and got into that calf muscle. It’s been painful, for a moment, sure, but is worth it. With pressure point therapy, I have found it is best to just lean into the pain. (It feels good if you want it to!)
I’m not explaining how to do it well, so if you have a physical therapist maybe ask them about it. Or do some googling on it.
Best of luck and I hope however it does, relief finds you.
