Hi, Babs17. I don't know if you'll trust my opinion on this one either

but... I had it RFA done in December prior to deciding to do my surgery in Feb. The procedure itself was fine - far less painful than steroid injections. Just a little sore the day or two after. After my steriod injections, I was in bed and feeling like a train wreck for a few days. I'd go for the sedation if they're willing to give it to you. I did. The procedure didn't hurt, but your muscles jump with the stimulation and I'm kind of a nervous nelly and it creeped me out. I had my finace draw on my back exactly where it hurt near my spine and the dr. doing the procedure seemed happy to have the help. Because you'll be laying down on your stomach for the procedure, I'm assuming, do the drawings (he did dots and oval with a sharpie) laying down, too. That way the skin is in the place where it hurts. Does that make sense?
I had absolutely no success with it. But! you might! I'd say it's worth a try as it really didn't hurt much afterwards.
Good luck and I REALLY hope it helps you. You need a break! - Margaret
