I'm so glad to have found this forum. Although I'm aware that I have severe arthritis in my spine, I had a lumbar RFA one week ago for ongoing pain on the right side (I've been having epidural injections for two years which have helped with sciatica issues on the same side). Four days after the procedure, I was awakened with excruciating pain on my LEFT side! It is finally subsiding a bit, but not totally. Has anyone experienced something similar? What was the outcome?
