What did I do to my ankle this time?

Let me fill you in. I was in dance for 6 years, sprained my ankle badly twice. The second time I tore ligaments in it; made a lovely crunching sound. Tonight, being the graceful lady I am, fell down the stairs and went over on the same ankle (it's been weakened from those previous accidents) and again, a lovely crunching sound was hurt. Now my ankle hurts like a SOB and there's a slight tingling sensation. So, yeah. What's up. I've got ice on it already.
