Hi Nancy,
I was in an automobile accident years ago, as a passenger and we got rear-ended while stopped. I had terrible pain in the tail-bone area for years. My pain management doctor wanted to do the Radiofrequency spinal rhizotomy, and my MS Specialist said NO!

I ended up having a Caudal Spinal Epidural with lysis of adhesions. That was not too much fun, but better than having Radiofrequency waves that could cause accidental, permanent paralysis, as a side effect. JMO

I now have Caudal Equina (narrowing) from the tail-bone being shifted inward, but not broken. I used to hurt so bad when I sat down, I had to use a soft balloon ring to sit on.

I also found out I have an unusual large and long tail-bone (MRI). I can feel it protruding even though it shifted. I am thin so that is why it protrudes more and it is large.

I don't know what spinal area you were going to have it done for, but there are other choices for pain. This is the latest thing that they seem to be pushing. I never had it, just offered it. Good luck with what you decide.
