I've developed a.sudden word pain in the back of my thigh. Like a tightness/soreness even when I'm just laid still. It doesn't hurt too much when I walk. I've convinced myself it's a blood clot or something and I'm panicking. The tiny logical part of my brain is saying it's might be a pulled muse or something. Its not red or hot or anything. Just a bit sore and uncomfortable. Can't seem to find a position where it's not hurting.
