To those of you that have had stress fractures, how long did it take until you could no longer feel it with walking? I am at 3.5 weeks and hardly feel it at all when I walk, so of course it's tempting to do the minimal time frame of rest but obviously don't want to reinjure it. Just wanted to hear other's experiences (when you stopped feeling it, when you started running, etc). I know it's different for body regions.
