How many blocks does it take for remission, no one has that answer. Some people have had 15 and no remission yet. Dr's can only hope, my Dr at the beginning was hoping after 3 mine would go into remission but I still have RSD as bad as the beginning. Remission is a hope that it goes to sleep for a while and you don't realize you have it/or feel it. You would feel that you were cured, at least for the moment. Some have gone into remission for days/weeks/yrs, each person of course is diff. As far as taking neurontin any longer once your in remission, that would be a docs call. Are you back taking it again, I know you had stopped and asked me why I take it and if you should start again. You should stay on it until the doc says not to.
And yes you are a lucky one, you can work/function in everyday life. I can't, I can hardly drive, can't do large shopping alone, I only have the one arm that works. So yes you are a very lucky RSD patient. I hope it stays that way for you, you just might be one that the blocks help.
Hope your day is better today
