You can find doctors in your area by what they treat on Vitals.com. Good luck!
You are asking two very different questions...
Do you have an opiate addiction?
We have an Addiction/Substance abuse board...
But there are Drs. who are called Addictionologists that treat pain in previously addicted patients..
Most likely someone who is both an addict and in true pain will be put on something like Suboxone, Subutex, or Methadone...
Good luck..
