Hello and welcome. I'm sorry that I cannot answer your question, but wanted to provide some support. I don't know much about suboxone, but that the psychiatrist I see is certified in prescribing it and that Dr's who prescribe it have to be trained specifically.
As far as the other....I'm sorry you have had so many Dr's, but it may be time to continue looking. Perhaps the PCP can recommend someone to help you. I don't heal well or respond well to most surgeries (most fail), so I can understand that part well. I also understand the CP very well....so we do have some things in commmon.
I think if this were me, that I'd start looking again...even if it meant a very long drive to find a Pain Management team who will work with me.
I wish you all the best!
