I’m suffering again and also in my right heel. It gets you down doesn’t it? Mine went away for a few weeks after I’d been in hospital for an operation and was only doing very light exercise. As soon as I went back to my normal routine it came back. I think I might go to a physio because I’m not managing to get on top of it by myself despite using orthotics and stretching it and also rolling it over an iced bottle. Good luck with yours OP. If you do find a cure please let me know!
