Hi Julie,
I am so sorry to hear how much you have struggled with your RSD progression. I encourage you to go to your block rested and relaxed. I think they help a lot to slow the progression (in retrospect). I had about 7 lumbar sympathetic nerve blocks in the course of about 6 weeks and after I quit having them, my RSD has spread to the bottoms of both feet up both legs and to my hands (in 3 months since my RSD began). I am hoping for another series of injections soon, since I am not willing to have the SCS due to so many bad things I've heard regarding outcomes of those who have had theirs.

It is important that you try to be as relaxed as possible. Make sure they numb you for your IV (have them us a pediatric IV) and sedate you for the procedure to avoid as much pain as possible (anything that might hyperstimulate your already stimulated sympathetic nervous system).

I am so sorry that you are going through this, but am glad you have found this forum. We all consider ourselves family here and each have our own story to tell and our own perspective with this insideous disease. Best wishes to you. Please let us know how your block goes on Thursday!!!
