Or in my case, “Which came first, the locked up/completely inflexible left ankle joint or the left tibial stress reaction?”

I don’t have answers, but I now have a ton of PT exercises that will fix what the therapist saw as a major problem “Of course you are going to get a tibial stress fracture if you run with your ankle completely locked up like this . . . but I can’t tell if this completely locked up ankle joint was caused because you have a tibial stress fracture . . .”

So, first order of business:  get left ankle flexibility, stat.
