I have went for a few pain doc opinions and the range of treatments I have gotten from each have been a huge difference. Each one too had a negative view of the other pain docs direction. My point is I often feel doctors will do what they do a lot of and not look at the individual often as everyone with rsd is different. I am not saying this for all doctors but just some. I am confused at who told you to go to another pain doc about the scs? So that pain doc felt it was a no or he wanted to see what another doc felt? I understand as when I feel worse I am very reluctant to try the treatment again. I wish I had an answer for you but if it were me I would ask the doc if this block goes bad like the other what will you be able to do to keep me comfortable and then what would be the next step? I asked that to a pain doc about if the procedure they had suggested went bad which was more then a block but not the typical rsd treatment course and my fear was being in worse pain cause that was a possiblity. Also I would go for another pain doc apt and if possible to really see if they work with a lot of rsd patients. Feel better
