what can you do when you have tried everything and nothing works?? You are told its degenetive bone

I was diagnosed with fibromyalgia, then degenetive disc disease, spinal stenosis, have tried large amounts of oxycontin, oxycodone, epidurals, i take cymbalta, shots, fentynal patches, neurontin, lyrica, and physical therapy, nothing seems to work, now they say........sorry, nothing we can do..the pain clinics here in Tucson stink..there has to be some relief. I need to get some sleep!!!   I have tried ambien, ratidine, xanax, you name it, I tried it....any suggestions. My problems are in my lumbar, sacram, down both legs and across both cheecks of my butt.......I had  a mri but it showed the diagnosis.
