Welcome to the forum Ikd,
I've had facets, epis, caudal, ablations ... To me, the pain is about
the same for all. The local anesthetic stops the sharp pain. All that's left is some ouchy dull pressure-type pain.
Versed does nothing for pain. It just helps you relax in small doses; it's used to give you amnesia for the event in larger ones. I won't take it. I know what's coming, prefer to have a clear mind.
Arthritis can push on nerves and cause pretty bad pain. I've had lots more of that since being in a wreck. I've got scoliosis too, but that doesn't seem to be a big problem.
I get some relief from tramadol, also a TENS unit because a lot of the pain is from muscles along the spine. The radiating pain I get is from spine, and some of the injections, especially at L5-S1 or caudal, help that for a while. My muscle pain beside the spine feels different, but it's no less painful.
