Hi annhere. I was offered a sympathectamy along with tos surgeries on both sides in september, as the surgeon did not feel I would find enough releif from the tos surgery alond due to other issues. I have spoken to others who have had it.....Yes living with pain sucks, and drives us to do alot of things..IMO it is not worth it, the side effects can be horrible. Please refuse me for being VERY blunt and I may get eddited for this but one of the people I spoke to about having this procedure after his tos surgery was and I quote "I would rather slide down a pole of razor blades everyday and use my balls as breaks, than go through this procedure again" sounds harsh...but was true for him. Also there is an increased chance of getting CRPS having this surgery done after your tos surgery...even more painful than what you experience now.
I considered the surgery....but declined, not because I enjoy the pain...but enjoy more pain and discomfort more. Good luck on your decision.
