Re: Please read
The situation regarding pain medications and thus, pain management doctors seems to be constantly changing these days, and laws do vary from state to state...but usually you would just find any specialist that i covered by your insurance carrier and call to make an appointment.
If your state is one where you have to sign documents regarding the management of your pain meds, I think you would just have to tell them you were being treated by another pain doc but had some issues -- you don't feel he is listening to you, or whatever it might be....use whatever reason you have that doesn't make it sound like you are a "drug seeker"....and explain you want to be treated by a different doctor in a different clinic/medical group.
I can certainly understand why you'd be reluctant to have more surgery. Perhaps you'll want to find a different hospital so you won't run the risk of having this same anesthesiologist --
