P.D.
UGH! I am so sorry this happened to you! I was a 'chronic' ankle sprainer. I would probably get it checked, but likely it is just a sprain. I heard mine crack, etc when I twisted it, but I never had a break. About 3 summers ago, I actually did them both and ended up in two walking boots for the whole summer. SEXY WITH SHORTS! One thing I would HIGHLY recommend that NO ONE, not even the dr., told me is to do a little physical therapy afterward. Since I did PT on mine, I have not sprained it again. That is HUGE for me! Good luck!!!
btw, if you are only doing an ACE bandage, I would switch to a walking boot. You need to immobilize it.
