First of all, keep your chin up. Thinking bad thoughts stresses you out and only magnifies your pain. I know it's easier said than done, but I have lived with a degenerative spinal disease for several years now and I know.
As for pain, the most important thing is to find a good rheumatologist. Mine has never been concerned about any addictions to medications because she insists that if you are really in pain, you do not get the euphoric effects that someone without pain would get and therefore you do not get used to that "high" that people with no real pain experience. My doctor has tried several different drug treatments with me. It started with Vicodin. Since then I have used Percocet, morphine, Soma (muscle relaxers), Oxycontin, spinal injections and am currently on methadone. That is about as strong as you can get.
If you cannot find a rheumatologist or an orthopedist (whichever is better for you) who feels comfortable prescribing these kinRAB of medications, ask your PCP for a referral to a pain management specialist. They have some new things available now--one which is an implant (kind of like a pacemaker) that is input under your skin and delivers a steady stream of a medication that specifically works for you. Every so often, the doctor will need to refill the disc, but that does not require any additional invasions to the body.
I hope this helps you. My best advice is DON'T GIVE UP. I looked for years before a doctor finally diagnosed me correctly. Remeraber, the doctor you see works for you. You do not owe him or her any kissing up in order to get what help you need. If they expect this, MOVE ON!! Good luck and remeraber that help is indeed out there.
