About a mile into my run yesterday I turned my ankle pretty badly. I think I heard a cracking or popping noise and for a few minutes it hurt a lot. HOweer, after walking for a little bit it felt a lot better, and I eventually started running again. The pain went away after a mile and I ended up running about 10 more miles to finish the run, finishing with no pain. When I stopped running though I felt my ankle starting to swell, and despite icing a little bit that night, there was still swelling and pain come this morning. I opted out of doing my morning run for fear that I have some serious injury, but then again can it really be that bad if I managed to run 10 miles on my ankle after I turned it? Anyone with advice or experience on this sort of thing would be appreciated.
