I don't really know what happened, but my ankle started to hurt out of nowhere. I don't do any sports, and I wasn't doing anything physical at the time. I was sitting with one leg under the other on my couch, playing around with my iPad. I tried to walk, but then it started to hurt to the point I had to hope on one foot. It's been about a day since then and my ankle still hurts, and I can't put any weight on my left foot at all without pain being involved. I'm not sure if it was a strain or anything, but I just really need some help.
