Well for me my nerve block which was done with flouroscopy increased my pain in the rsd area it was for. That is why my pain doctor did not have me do the scs with the some fear that it would increase pain instead of settle. I have met others this happened too. My pain doctor said for some people this actually revs the nerves up instead of settling them. This because the pain is in the brain and not in the spine. There is a name for this and that is when pain meds and similar may work better then blocks or other treatments like that. The area in the spine where it was done was tender for me but not so painful. I will say my body even in non rsd areas is so sensitive where things that did not used to cause pain does now. Some may be because I am so careful to not knock any area that my body is not used to any harsh movements or forse. Where is your rsd? What other treatments have you tried and are you on meds? Welcome to the boards though I am sorry for your pain.
