I see you've not had any comments here for nearly 3 years, but that's how long I've been doing RF ablation/facet injection. My 1st pain management doc that did it for me 3x (2018, 2019, 2020) retired; he was addressing C3-C8 --basically all the cervical vertebrae, both sides. It helps reduce the pain of migraines A LOT, but I still have them... back to 1 Fiorinal/codeine from 4-6, plus Imitrex. Other preventatives I have tried included: Botox, CGRPs (3 different ones, they suck), beta blockers (made me dizzy), tricyclic antidepressants, Toxpamax, and I'm sure I've forgotten some things. I've tried melatonin (causes migraines), feverfew (yep, causes'em too), mega-B vitamins with CoQ, ginger, butterbur, caffeine/not, etc and so forth. Thanks to the State of Texas making it possible only for Pain Management docs to Rx pain meds, I "fired" my neurologist -- the PM did the same stuff she did and more, so why bother? My 1st PM doc retired in Dec; my Cervical stuff "wears out" in July-August, and I'm not sure about the new PM doc. She's "in" to ketamine, and sedating for all RF procedures -- 1st doc was okay with me going sedation free. The L4-S1 procedure doc 2 did for me with ketamine -- the procedure was okay, I guess, but the ketamine recovery was a 2-dimensional nightmare -- couldn't move, didn't know what was going on, couldn't understand anyone about anything (words didn't make sense), and I was apparently staring at the ceiling tiles without realizing what they were with no depth perception... While it might take 8-10 procedures with ketamine for any effect, I'm not doing that again, especially after nearly choking on stomach bile. The nurse tells me I was "very quiet" for being under ketamine, I think I was scared silly and doing the "perfectly still prey hiding" routine. I know there are better sedatives, my colonoscopy was nothing like that... so we'll stick with that.
