I walked 1.5 miles on the treadmill yesterday and 2.1 miles this morning outside. That was enough to fire up some part of my leg on my left side. So, for the next week, I'm not supposed to walk. Or run, of course. Nothing from a standing position. Bike might be an option, but given the pain when attempted at the physical therapist's office, it doesn't seem very promising.
I bought a heel cushion (insert) for my left heel at the physical therapist's recommendation to see if it makes a difference in walking... It does, but I still feel the pain.
