Suggest Remedy For Severe Pain In Spine And Ribs

I have severe pain in my entire spine and ribs. I have been diagnosed with Chrons disease when I was 35 and have been in remission since 2003. I also have chronic L5 disc pain have had two surgeries to correct and things just got worse. I also CRPS chronic regional pain syndrome of the right leg and have a stimulator in plant for back and lower leg pain. I do have constant ulcers and abdominal pain. I have taken numerous meds for the Chrons disease, but I am getting severe spine, leg joints and rib pain when I lay down for more then one hour to four hours. I awake with such pain I can hardly move. But getting out of bed usually helps reduce the pain with in 5 to 15 minutes. This has come on over the last 6 months gradually and seems to be getting worse. What can this be and who should I choose doctor wise to start looking for help?
