Okay. This was unexpected. I think I have a stress fracture in my right foot. I've been barefooting since mid-July and have (I thought) been careful not to add too many miles at a time (no more than a half-mile per week) but I think I have hurt myself. It doesn't hurt as much while I'm running, but afterwards I'm in a fair amount of pain -- enough that I sometimes have trouble getting to sleep at night. I've seen a doctor and the X-ray was inconclusive. My MRI is scheduled for next week. I won't know the results until the 29th. If this is indeed a fracture, that'll be two this year: the first in my left knee from overdoing it as a shod runner between Jan. and April, and now this. What the effing eff am I doing wrong???
