Those are the procedures that I actually did. Granted, I'm pretty aggressive, and not intimidated by the anesthesia residents, so I probably did more than some people, but yes, these are the procedures that I performed. My 1st day I did a medial branch block, a trigger point, and a facet. The procedures are there. But like I said before, this is not as big of a deal that you think. I did an outside pain rotation, and though they were impressed with my procedural experience, it's not like I was put on a pedestal or anything. You're gonna need to do a fellowship to practice pain, and other things (like research, LOR's, etc) are much more important than doing 20 facets.
Also, some advice, don't ask that on interviews. People will get a weird feeling about someone who only wants to know the number of pain procedures available. One may think that you wouldn't have an appreciation for PM&R as a whole, and some attendings don't like pain at all, and that will really get you on their bad side.
