The cardio doc and my pain mgmt doc know each other and practice at the same facility , however the cardio knows nothing of RSD . I will certainly have more consults before I have any type of procedure . Talking to the two docs is like talking to one I quess , as they both suggest to see what the other one thinks ..... The procedure itself is only done at a few of the major hospitals in our region , so I will talk with specialist for this procedure at least before we do any surgery . The biggest stumbling block with all involved (myself , family , docs. ,etc.) seems to be the RSD and how it plays into this picture . Definately worried about spread as mine has gone from LUE to entire left side - head to toes already . Then if you exclude the RSD you still have the different theories on when to operate , risk vs reward is an extreme for both waiting and proceding . Sorry to ramble ! Take care and thanks for response...
