Hi Joby,
I also had the stellate ganglion block for my left leg/foot about 7 months after my foot/lower leg turned blue(ish), mottled and so COLD. Well, it was wonderfully warm and pink after, so it confirmed the RSD dx. It's important to go for it-I had no pain from the procedure at all, I only wish it had stayed nice and warm and pink You'll do fine. I've had a rough start and haven't been on in a long time, but this group is here for you. Keep in touch.
