I wanted to let you know that I have Bilateral TOS and I have been thru my 2nd surgery. I also went thru the, is it RSD or is it a nerve healing. My Dr and I tried all the routes, time, steriods etc and nothing seemed to really help me. I had feared that I had RSD starting and my Surgeon also suggested that I may have it in the works so he wanted to do a Stellate Ganglion Block. Like you I was also scared to death... I didn’t want to go thru another block or more injections but I also didn't want to suffer the consequences of RSD. So after pushing it under the table for a while I chose to do the block. I did have relief for 22 hours. Now I will be going for my series of blocks to try and put this in remission. Here is the link to the thread if you are interested in reading it... But I do suggest you at least go and get the block. It will help diagnose you either way and it is better to know if it is RSD now than later...
