Well I sprained my ankle a week or so ago, maybe a day or two less and it's been feeling alot better.  But then I was pretty stupid today (in hindesight) and I think I may have overexerted it (high jumping).  So it's feeling pretty sore now.  I am DEFINITLEY not doing that again so what should I do if I ever sprain my ankle again and how long do I have to spend recovering?
Thanks in Advance.
(Also if this is relevant I fell when I was walking down the stairs, of all things)

Thanks, it wasn't awful and it started feel less throbbing about 2 hours in and was only sore.  I guess I didn't wait long enough, it's gonna be another week off.
