How To Cure Severe Rotoscoliosis?

I am a 39 yr old female with severe roto scoilosis, In 2005 after my son was born was when I started having bad back problems, I had to be on bedrest the entire pregnancy,and when I returned back to work, I was in such pain, I could not work my 8 hr shift, I went to my doc and he sent me for an MRI, and the report had slight scoilosis and Degenerative Changes, I have Severe nerve Damage L-4, L-5, But I kept working, In 2009 I transfered to a different Wal mart and they put me in the meat dept. lifting 50 lb boxes all day, i couldnt take the pain anymore, I had to take a leave of absence from work to try and get my back better, Shortly after I went on LOA, I found I was pregnant with my daughter, another Bedrest for 9 months and after she was born I had new xrays and the Doc said I have a 27 degree curve in my spine, I have had at least 15 Facet Injections in the last 3 yrs and thats about all any doc has done for me, My most recent MRI in 2013 shows severe scoilosis and I just had new xrays a few months ago and now My lower back has a 41 degree curve and my spine is twisting, and upper back is 27 degrees. I cant find a doctor that will help me with anything more than injections, and those only last a couple weeks, And i cant find a doctor to help me with any pain medications, because of all the people out there abusing drugs, people like me who truly need something for pain cant even get it!!!! PLEASE HELP ME
