Thanks everyone for your feedback. In terms of research, I didn't find any peer reviewed publications about rfa, but I did see that it is being done at an number of pain intervention clinics. Does anyone know of studies that report on it?

In terms of making it worse, all I saw was comments from people who that happened to. I appreciate the disappointment and sense of betrayal that would lead to. I wonder if those people had more severe disease then me. Dos anyone know if those same risks occur for more mild disease? Also, I wonder what proportion of patients have an adverse outcome (which is why I am looking for studies on it). I'm sure most of you have been as disappointed as me at the lack of research out there, however.
