Cathie,
Just call your PCP and have him/her check you out just to make sure you don't have a fracture. It's just better to be safe than sorry. And you know the old RICE routine.

If not here's the google: http://orthopedics.about.com/cs/spra...a/sprain_4.htm

I sure hope you didn't break anything. Don't do any extra supplements. You may mess up your testing by not having normal blood levels of the particulars.
