Okay, time for a pseudo-update: I have been doing some walking when the heel is tolerable and resting when its not (elevate, ice, etc...). I was able to hike the Deep Rock Quarry trail with Samson (my pup) yesterday, wearing hiking boots and I fell no worse for the wear. I can't wait for the doctors to figure out what is going on so I can do more. Cycling seems to cause more harm to my heel than good, though it greatly lifts my spirits. More to come after...
