Do you have to go to the clinic you were referred to? If not, try to do as much research as you can to find a good pain management doctor. Look on the internet, etc. Some sites have patient reviews on them. I agree with the previous poster. I like to see the "top dog". I couldn't get to see him at first because he was so booked up. I have to schedule my appts 2 months in advance to see him, but it's worth it.
Sorry for all of your struggles as I have been through most of the same things.
Very good luck to you!
