As I go back a re-read your post, it strikes me that the big problem is his attitude. I can understand a doctor being frustrated when a patient is (in his mind) refusing to cooperate with what he considers to be the correct treatment. But being rude and dismissive doesn't strike me as the way to handle it!!

It's a conundrum. We have the right to make decisions about our own health care. And yet, what's the point of having a doctor if we don't follow his/her advice?

If a doctor simply can't work with you when you're not ready to try new therapies, or decide to discontinue some, then I would think he'd tell YOU that you need to find a new doctor!

What's tricky about MS is...that it's tricky. This isn't a case of a doctor saying "You won't take the pain pills but you're complaining about having pain."

I hope you can find a neurologist who will work WITH you, even if he/she feels you're just treating your symptoms. We have a right to do that, also, I'd say.
