Oh my GOD!. I am really feeling your pain.
A few weeks ago I took a wrong step on stairs and damaged my ankle.. there was swelling, nothing on Xray, but hurt like crazy and at first I thought I broke it.. I mean it, I have fallen on my ankles a lot of times, but never this bad...
First aid - 3/4 vodka 1/4 water - soak a cloth, put it all over and wrap it up with elastic bandage.
Next aid - take a cabbage leaf - big juicy one, beat it up with a meat hammer or anything, so the juice gets out of the leaf, wrap again.. I put those on for the night - in 2 days no inflamation anymore. Vodka really helps, believe it or not.
Hope your leg heals well.. mine still hurts a bit even though it was at least 2 weeks ago when I fell..
I play games with Hulk and a fire breathing dragon.. Love it.
