Hi. I think it really depends on the person and getting proper and quick pain control treatment. Though my rsd has spread I am able to do so much more then when it began and have way less crying from pain days. There was a time I could of never done what I do now. I can laugh sometimes and am out of the bed full days where as the first months of this I was crying from pain and barely could walk. I do get frustrated when other areas have been hit and still at the pain level/limitations but I am trying to remain hopeful in continued progress even if it is slow but I am hoping for faster now. Don't give up and try to stay in the day. As my pain doc says do what you can do on the good days and on bad days do the best you can.
