Yeah, like it's terrifying that people can go through a decade of education and training and still not have a grasp on some of the basics of their field. I expect to have to explain my migraine because I have a pretty rare subtype (like I'm the first person my neurologist has treated), but I shouldn't have to explain why I can't take a medication that says on the pamphlet "DO NOT TAKE IF YOU HAVE [CONDITION I HAVE]". I'm not expecting every doctor to understand a neurological condition that affects less than 1 in 8,000 people, but I do expect them to accept that I do have it and not treat me like I'm being uncooperative for not being willing to risk a significant increase in risk of life threatening side effects.
