I have lumber facet joint arthritis, L4 and L5 with most pain on right side. At the start of the year i had a facet joint ablation where they burn the nerve to the facet joint which is a source of pain from this type of arthritis and can reduce pain quite alot. It worked really well for me but now 7 months down the track its starting to come back, bugger. I was told that it should last about 12 months as the nerves can grow back but was told that sometimes it can last for years. Its not a cheap procedure and will ring the doc who did it back and see if i can get it done again for free??? Anyway has anyone else had this procedure done and been successful for pain reduction but has had the pain return within 12 months?? I must have run over a black cat sometime. cfs wise i have been feeling good after treating this sinus infection and have been sleeping well also, but now the dam back is playing up, if its not one thing its another. Im sure when i get my back sorted i will go through a bad run of insomnia, lol?? cheers!!!
