I have a similar problem and was wondering the same thing. My sprain is much fresher (not a very serious sprain) about 2 months ago I did it but I still feel pain/discomfort in inversion and I certainly favor it. If I'm walking on snow or an unstable surface and my foot wobbles and pronates, inverts I get the pain/discomfort and it feels like I'm re-aggravating the injury. Thanks for asking the question John.
