Help find a pain management doctor that treats fibromyalgia?

I have fibromyalgia a need help finding a doctor that will treat it with the same medications as my old doctor. I changed insurances, and my old doctor was prescribing me 80mg of oxycontin, and 120mg of oxycodone for breakthrough pain. I would appreciate it, if someone knows of a doctor in sacramento area and greater who could maybe treat my fibromyalgia with pain medications. Thanks very much.
