I am confused; you were going to doctors for pain management and changing your primary care physician for your other stuff it sounds like. I don't know why you were changing your primary care person and/or if you were seeing two sets of doctors or only your old primary care person for the pain meds?

If your back is still having problems, I would make an appointment with a specialist to deal with that problem. If you are going to a clinic for all of your various doctors, or your insurance is in the way or something of that nature, I would sort out that problem independently and get a primary care physician who can help you move forward with your ongoing issues while also being aware of your back issue.
