I had two MBBs done at L4-L5-S1 to determine the source of approx 30 years of lower back pain that has grown worse. The results of the MBBs ( required for Medicare coverage ) did show I was in the 90-95% group where an RFA would bring relief. Had the RFA done and it had zero effect on the pain. My MRI does show artheritis beginning at L4 and progressing down to the S1. I was on Meloxicam for about 5 years but has since become ineffective same with 800 mgs Ibuprofen as needed. I stopped all the meds. I have tried PT and Chiro but no improvement. I was told that I could have an Epidermal but I have had two of them in the past and I said no to that. I am scheduled for a consult with the PA about an RFA do over or Facet Joint Injections. Any comments ?
