lumbar pain

I have unbearable lumbar pain. I had a double fusion in 2022. I now have pain in my lower back. I have tried everything possible: injections, ablation, PT, lumbar massager, pain pump, etc. Both my pain dr and PT tech said I would have this pain forever. I can't live with this pain. I know this is a reach, but does anyone have a suggestion to help this pain go away? It has affected my quality of life immensely. Lots of tears! I just want to be pain-free! Maybe I'm asking for something that isn't possible. Any ideas would sure be appreciated. I love this site with all the knowledgeable, nice people! Thank you!
