Well - this morning at 4:30 when I got up to take a quick potty break, my heel hurt so bad. Before I actually got out of bed for good at 10:00 I stretched and stretched and stretched - and it didn't hurt very much. The bad news is that it isn't completely pain free (boo!), but it is about 50% improved - - - but I don't know if it warrants enduring a few more scraping PT sessions (very difficult decision).
Sorry to bore you with one heel update after another, but thanks for your encouragement and advice - always appreciated! Have a great day!
