Soooo, about a year ago my calf freaked out on me in the middle of a 6 mile run. I took a few weeks off, then eased back into training for a half-marathon. Ever since that run, my calf/shin has been pretty sensitive... gets sore easily, especially when I run on sidewalks (which is not often anymore).

I have a history of tibial stress fractures from being overtrained by a college coach, so the soreness kinda freaks me out.

Anyone have an experience with this? Or input... input would be nice. :-)
