Ray, isn't it amazing how these "minor" inconveniences turn into major problems out of nowhere? I guess a tendon will quiet down quicker than a stress fracture, so here's hoping for an inflamed tendon, eh?
I have to ask what why you were compensating for your heels, were they sore as well?
Anyway, good luck. My guess is you're going to bounce right back...
Enjoy life, this ain't a rehearsal...
