Well that is what happened to me and I can walk on it but until I start running it starts to kill me and can't even walk after that, but I did not sprain it cause I would no if I did or not. But it is BOTH of my ankle and hurts all around my ankle and on the bottom where my heal is. Ok but back to the ?. Well if I were you(this is what I did) I would take a bucket of cold water(half full) and then take th other half and put ice in it. After you do that put your foot/feet in it for only 5-10 minutes then take them out and rest for about 20 min. And do the same thing once more. I got this from a great doctor. Hope you feel better!!! I feel your pain!!!
