Dr, Marc Lynch he has some offices in diff locations you can look him up on internet some of his offices are in chino or ontario, ranho cucamunga, and more. has his own pain surgery center. But if you want pain meds its really hard he wants you to try everything you can before taking pain meds. Also he does injections and pain stimulators and pumps. believe me I was so happy I did not have to take drugs anymore for pain. it is really scary at first and you have to go through withdrawls before you get one put in but you start getting part or all your life back. good luck and God Bless
Your best options are your insurance website and perhaps recommendations from the anesthesia Dept at your local hospital. My PM doctor was also an anesthesiologist who specialized in CRPS .
