I have to say I agree.
I'm in a similar situation. I've had a major gynae op and have evidence that points to a different outcome to the one I have been told but they refuse to discuss the situation with me.
Pretty much the attitude is that they are doctors, I am a patient, and no matter how many books I read and how many case studies (i am a member of several medical research sites) I present them with all I get told is that what I am saying is not possible and does not exist hmmmmmmmmmm
so stand up for what you believe, I even took the line of saying "look humour me, investigate to prove I am wrong" but they wouldn't even do that, so now I have an official complaint in progress.
