glad to hear of the progress; wish you continued wellness.

I fall over every now and then, too, usually to do with my knees going sideways, but I can't say as I can always pinpoint why. Even though it's not direct support, a bit of ankle support with boots rather than shoes has always helped, as has strength training the muscles that holds the whole mess together. I can even dance, now, if I wear boots sturdy enough. Talk to the PT person once you get one? I bet they'll have good general advice.
