Hiking on the Applachian trail two weekends ago I must have caused a stress fracture in my foot. It didn't feel that painful so I didn't pay it much attention. This past weekend the dog got out of the back fence and I was forced to chase it down. I was barefoot at the time as I was trying to give him a bath. Running barefoot on a sidewalk with a stress fracture isn't a good idea.
....and down I went.
Still, I will remain hopeful.
