I had the Radio Frequency injection done at least two months ago and I also had the same issue with the RF causing even more pain. Turns out the RF procedure can be such a shock to the body that it can set off every nerve in your body and that is what happened to me. I was actually throwing up the pain got so bad. The Dr told me that in rare cases, the RF causes every nerve in the effrected area to become inflamed, which causes the extra pain. They said that to treat this issue, I should go on steriods but instead we increased my pain meds because the pain never went back down. My pain levels have remained increased, the procedure was extremely painful, and now I have back pain that wont seem to go away. My advice, DONT DO THIS PROCEDURE!!! PLEASE, DONT MAKE THE SAME MISTAKE I MADE. If we all learn from my mistake than maybe I wont regret getting the procedure done and Maria, I'm sorry to say that I think you two will have to do damage control.
