I Am A 28 Year Old Female Who Has Had

I am a 28 year old female who has had 3 spinal fusions, complex regional pain syndrome, an undiagnosed autoimmune diseases which the biopsy showed that I have no sweat glands in my upper thigh while the lower portions were normal, a slight bludge in my L-3 as well as C-4/5, stenosis, and have tried every injection, implementation/device, medication both traditional and holistic, physical therapy, eastern and western medicine with either little or negative effects. I live in constant pain, have been off all prescription medications because of all the adverse side effects and I can't seem to find any treatment that makes me comfortable or gives me any quality of life, what can I do at this point to help ease the pain or treatments I can pursue, or doctors or specialists that would be able to help my case?
