Okay so sometimes when I stretch out my legs, I'll get an extreme pain and my toe sometimes dislocates from it. It feels like my leg is going to snap, it hurts really bad. I'm not stretching it weirdly, sometimes I'll just be lying with my legs straight out and pointing my toes and it happens. I used to be in ballet a few years ago for five years, I'm 20 now. Does anyone have ANY idea what this could be?
