UNC has a terrific PM group. I do think you need a referral, but if you can travel to them, they are VERY compassionate and have the pharmacy onsite. It has been years since I needed their help; they may have technological innovations these days and/or partnerships with universities in your specific area to help alleviate the physical need to travel to them often.
Call the hospital and ask to be put in touch with their PM Clinic. Like I said, you will likely need a (strong) referral, but your previous doc should be able to provide that to you. I found they were MUCH more willing to be aggressive with the management/med end of things than any other doctor or group I've ever seen. From what I have heard from others who currently use them, if you follow their "rules", they are by far the most compassionate of any of the PM groups in all of NC...
I know this is a bit late to your OP, but hopefully it can be of help to you or someone else! Good luck!
