Maybe he just needs to see it on paper. I would write it all out for him, listing all the follow up and meds and such that you need after the infusion. You can even list costs if you know them. Then bring, fax, or snail mail it to his office so that he can actually see it. Sometimes that helps.

I'm sorry you have to put the fusion on hold for now, especially since it has been helping you. Hopefully, you can start up soon.
