Hi!
I've had many blocks which were done by two different doctors and I was never put to sleep or given sedation. Many people on here have been so I guess you'll find out tomorrow. I didn't think they were that bad. Most of mine were for my legs-lumbar sympathetic blocks. I had one or two for my arm-glanglion blocks. Which part of your body are you having this for-upper or lower extremity?
My first doctor who did them would make me stay in his office for a few hours. The second doctor who did them let me leave immediately. I guess it depends on the doc, but this was my experience. I hope it helps you. Good luck tomorrow and let us know how you did.
Sharon
