Would a specialist you've seen be doing the procedure or a PM (Pain Management) doc?
I'd go over the options (all that were offered to you) with a doc and ask about the pros of each procedure and what makes it a plus (with your spinal condition) over the others.
I'll give it more thought. I'm sure there are others here who will offer far better insights than I have at this wee hour
