I got the results of my follow up MRI yesterday. The heel is still broken but "may indicate some healing". But good news, I have not made the fracure worse.
No MRI photos to show this time, mainly because the image quality was CRAP. Really fuzzy and not crystal clear like the first MRI was. I think I make a pretty good faux-radiologist though, because I could still make out the crack with my own, uneducated eyes. That, and I could feel the fracture while swimming. That shouldn't happen.
So all these races over here to the right? ------->
They're not happening. Not a single one.
