You deserve a pdoc who listens and is willing to look at different meds if the ones you are on are not working or have too many side effects. Even if your not happy with them they should listen, it's your quality of life that's supposed to be their main concern not what easiest for them.

Don't burn the bridges but do look for a pdoc that accepts Medicare, it might be a long wait that's why I suggest you don't burn the bridges until you've seen the new pdoc no matter how tempting it might be to tell these current Pdocs where they can go.

Do talk to your T about this, he/she might be able to get the dialogue going with the current docs or at least tell you what would happen if and when you find a new pdoc.
