According to the California Medical Board, most California County Medical Societies
will provide physician referrals. I suggest that you contact your
County's Medical Association -- explain your situation -- and ask for a
referral to a physician who has both the training and experience to
deal with both aspects of your current medical situation.
If no single physician is found with those qualifications -- perhaps
they can refer you to an OB/GYN and Pain Doctor who have worked
together -- treating patients in your situation.
The above link provides contact information.
