And welcome to the pain boards. I'm sure someone will have a more personalized answer for you, as you can see I'm on the other side of the country from you. You might benefit from searching these boards for tennessee pm and see what comes up.
Also most of the rest of us will be happy to help you if we can on the more generalized questions about pain management and clinics,
There is a huge variety of what different pain clinics offer, and you really dont know what yours will focus on until you have an appointment, But I think the best ones are the ones that offer many options, not just one, and see you as a whole person, not just a pain patient.
Good luck to you and I look forward to reading more of your posts.
