Sorry about the ankle!
Wasn't today about fun? It happens every so often, I have 18-19 years on ya, and feel your pain. I refuse to slow down, you just can't. The words of Tom Petty "You never slow down, you never grow old" I live by them! Ice is your friend tonight, stretches and all that when you can. Tiger Balm is a friend of mine too.
In all my years I've sprained the right ankle twice (never let the first heal), and the left once. Both times it was really weird conditions. I think my dogs have helped me strengthen my ankles, they always dig holes, traps I say....and I'm always stepping in them. LOL
Rest up bud and relax tonight.
