I'm sorry that your regular neurologist is closed/on vacation/dead until after New Years, and that you don't like the doctor covering for them.
But I'm not some sort of neurological urgent care. Showing up at my office without any old records because of some acute issue you need addressed, and planning to return to your previous doc as soon as they get back, doesn't fly here.
I mean, I have my own patients to take care of, and it's not like you're planning to stay with my practice. You make it pretty clear that you're just coming for me to patch things up until Dr. Wondrous returns/detoxes/is resurrected next week. There's a doctor on call for him. SO CALL THEM, NOT ME!
And I'm really pissed off at your internist for participating in this. He tells you to come see me until Dr. Wondrous comes back, because he doesn't know what to do, and he doesn't know Dr. On-Call, and so he sends me a note that says something like "please manage meds until regular doc returns" or "patient has had neck pain since 1972, please do something about it in Dr. Wondrous absence". These notes are especially grating when written by an internist who never refers to me anyway.
Of course, I have none of your past records, and Dr. Wondrous staff is gone, too, and you have no freaking idea what you've tried before, or if it worked, or what tests you've had done.
This is why we have call groups people. I'm sorry if you don't like the person who covers for your regular neurologist. Tell them when they come back. But I am not providing temporary coverage for them.
