Technically you can't be cured, as there is no cure for RSD. There are only treatment methods that either do something for you or don't, and in most cases there are lasting effects or there is lasting damage (like a limp, a serious handicap, limited ROM, etc...). It's like saying an MS patient, an aids or cancer patient is "cured". "In remission" is a far better way of putting it with a condition as bad and as poorly understood as this.
