Hi Hope,
That sounds pretty typical because they probably have to book rooms for procedures ahead of time in the hospital and it's probably not cost effective to cancel procedures at the last minute. Which obviously doesn't help a patient who is in your predicament. Are there any activities that you can engage in ahead of time that you know will flare-up the PGAD? Flaring things on purpose doesn't sound like an appealing route to go though.
Are you having a block with just marcaine/numbing agents but no steroids?
I think you have very good reason to wonder why you would want to have a nerve block to S2 if it's associated with pain in the back of the legs and that's not where your pain is. My understanding is that S2 also feeds into the pudendal nerve, so that might be one rationale to try it. There could possibly be other nerve involvement though such as meralgia paresthetica.
https://www.mayoclinic.org/diseases-con ... c-20355635 Another nerve to consider with PGAD and anterior thigh pain is the genitofemoral nerve. I think it is easier to block than the pudendal nerve because it's not as deep and it's just a sensory nerve without motor involvement.
I don't think interventional radiologists typically do consults with patients. They just perform the procedures that other docs order. It's nice that he was willing to at least answer some of your questions before hand though.
Good luck with your procedures. I'm sure it feels like forever until you have them. In the mean time -- might be worth it to try some PT. A good PT or manual therapist might be able to shed some light on your diagnosis.

PNE since 2002. Started from weightlifting. PNE surgery from Dr. Bautrant, Oct 2004. Pain now is usually a 0 and I can sit for hours on certain chairs. No longer take medication for PNE. Can work full time and do "The Firm" exercise program. 99% cured from PGAD. PNE surgery was right for me but it might not be for you. Do your research.
