Exercising atheists: I walk about 50 miles a week. Yesterday, after sitting for a while to grade papers for a summer class, I started to walk again and I began to feel what I would describe as a pinch in the leg. I do not know the name for the part of the leg. If I touch it, I feel nothing. Standing, nothing or virtually nothing. But when I walk, there's the pinch and occasionally it feels like a rubber band stretched too far and then snapping back. So, short of stopping walking (which I cannot completely do), suggestions? Particularly from those in health/biology fields? Where'd be a good place to look so I can figure out the name for the part of the leg and give a better description? Some warm/cold mix of applying a compress? How long to wait before saying, yes, I need to see a doctor about this?
(P.S.-sorry this isn't about agnosticism/atheism. But if I asked religious friends, they'd pray for my leg, right?!)
