Did you read any of Braingonebad's posts about the pain clinic and the drugs they have her on? She is, finally, having some relief. One is a patch and the other is a pill. Flector is one name and Robaxim is the other.
Here is one of the threads:

IMHO, you need a pain clinic. As you can see from Cathy's experience, there can be other solutions that are non-narcotic. I saw a post of her's the other day that said she could actually work i her garden without the horrible pain.
Your PCP is right that pain is a quality of life issue. You deserve to have it aggressively treated.
