I guess I can offer a little advice but more empathy as my foot has now regressed far enough that I think I’m subconsciously favoring it and causing other problems, so I’m taking hopefully a little time off to let it get better.
As for advice, I’d say make sure you keep carefully stretching it. You say it felt more stiff Tuesday than Monday. If you didn’t stretch Monday, even without running that day, should this be a surprise? You want to be careful so you don’t overstretch it and cause any damage but make sure you don’t neglect the stretching either. This is a lesson I learned the very hard way two years ago.
