I had one done by Dr Schwartzman's team back around 1990. Strictly diagnostic. It was NEVER intended for treatment. As far as I know, it's a well, it's not for treatment, but it does make some doctors some money! BTW, I had absolutely NO pain relief from my block(s), ever. (I had one or two lumbars as well). Not even for a moment!
And, Dr S, figured as much... (Since I already had rsd for 7 years).


And, as Sandy said, these can cause a spread!

Good luck to you, Lefty!
