Is what all the research I have seen says. That way there is a good chance of remission, or maybe even a cure. You are very lucky to learn this is RSD sooo soon, so make sure your getting the treatments needed to curb RSD.
For me it was about three and a half years before someone told me RSD. The vascular surgeon that told me that also told me that it was permanent because I had it sooo long. He said that the other vascular doctors knew fully well that what happened to me would cause RSD, and even if they werent sure of that, for sure nerve damage. It was to late for me to do anything about remission but I could have a go at at least keeping myself comfortable.
So get aggressive while you can.
