My ankle was sprained 10 months ago - it still isn't all the way healed. I asked the doctor about this, and he said its not unusual in a bad sprain to take well over a year to recover. I was shocked to hear that, but the research I've done on the Internet pretty much confirms it. Since I've had no setbacks on healing, excercise aids its recovery rather than impedes it, and its finely getting close to 100%, I'm convinced its just a slow recovery for me.
