Hi Gotoeden,
Have you gone to a pain mgmt doctor, someone who specializes in treating chronic pain?
I was going to a rheumatologist for my issues but he admitted my pain was getting to be more than he was comfortable treating and referred me to a pain doc. Perhaps if you do it that way, your insurance will cover it.

I know when I was first dealing with the pain, it was an overwhelming feeling of helplessness and often panic. And adding insomnia to the mix sure doesn't help. I strongly recommend a pain mgmt doc, he changed my life and made it manageable again.
All my best, Diandra
