I was listening to music, and jumping up and down. I fell down, and heard my ankle having a pop noise followed by some pain. I'm pretty strong, by that I mean, if I get an injury, I usually suck it up, and not tell anybody. I don't really know what to do right now. I wrapped my foot and ankle with those wrap things. I don't want to go to the doctor. What's wrong with it? What should I do?
