The worst part of the block for me was that I was in the room on my stomach for 10 mins before the doctor came in. My anxiety was off the charts and than I couldn't wait for them to sedate me. I am really apprehensive about the block I have scheduled for this Wednesday....not so sure I want to do it again. When I had RSD initially at age 36, I did 12 lsnb in a 3 month period without second guessing anything. I went into remission about 1.5/2 years later and slowly got back into my life again. I had one good year and than started developing a variety of health issues over a one year period that once again disabled me! After six doctors, I was diagnosed with chronic Lyme disease which took another 18 months of medication and severe weakness and pain to get rid of. I think the RSD coming out of remission means another battle/fight which right now I don't feel I have in me. Thanks Marleen...nice to be connected with you here!
