It doesn’t happen all the time, it seems to come and go for no apparant reason. It is happening again right now, and it only seems to happen when I’m sitting down with my legs crossed. I can feel something spasming in the back of my left thigh. It’s not uncomfortable, but it’s slightly worrying. Anyone know what it is?
