I just had my first RFA done on the 9th of October. Not so bad as far as the procedure went and I was awake, just given a little drowsy medicine. He burned or ablated 4 nerves. Exactly 2 weeks later, last Thrus, I was about 80% pain free!! And today, three weeks out even more pain reflief!! This has been a good thing for me as I suffer from bad facet arthritis in the L4-5 area. But it is so true, give the RFA some time to work...my Dr. said up to 4-6 weeks. A GREAT thing for me!!
