"when you say rolled outward, do you mean your foot/ankle or your body? IE, is the pain on the medial (inside) or lateral (outside) of ankle?"
My left foot rolled to the left (outward) as I went down in a screaming heap. The pain seems to be on both sides.

I'll stop the heat treatment---just did that once today (hot water in rubber hot water bottle). Once I heard cold/ hot alternating helps but I'll stop the heat.
Deep water exercise seemed to help a little today except when I moved too fast and resistance on ankle was
too much.

That ASO brace looks good--I'll see if the big box stores have such. Coincidentally, I have dermatologist Dr
appt tomorrow so can see if Health Partners clinic has such a brace also. It it fits in running shoe it would seem
that it would fit in by bike shoes..
