Soft tissue damage but nothing feels broken. Going to be on crutches for a few days at least. I think I hyper-extended it by tucking it under the foot brake, and my SIDI Armada's saved the ankle from flopping around with a break.
Some swelling and lots of black and blue today. I honestly think that the 512 mile ride home in that boot caused me more pain because when I put the boot on in my tent I was able to zip it closed so the swelling was under control, but when I got home to California 9 hours later the foot was swelled inside the boot and I had trouble getting it off.
I had blisters around the ankle and the lower shin that I didn't have in the morning and they had popped sometime on the ride, so needless to say, that was pretty painful.
Now I'm on the RICE regimen (Thanks to Sharif Massoud at Overland for this acronym): Rest, Ice, Compression, and Elevation.
Thanks for asking.
