Sorry to hear about all that, what a shock that must have been. Really, best wishes for recovery.

I'm still recovering from a non-separated AC sprain from a bike fall involving a brush-by pass (and a pick-up truck, not that that means anything with my sample size of one). It's been about 90 days, but I'm riding again as of two weeks ago, starting around day 75, and the rides are good. Sorry to say I'd guess your recovery will be longer. But there are brighter days ahead, just be patient and let your body and your doctor tell you when you're ready for more.
