I don't think that most doctors object to you coming up with ideas about your illnesses either, as long as they are rational ideas, and you are prepared to be flexible about them, and not dogmatic.
I always feel that I have a working relationship with my doctors. I'm expert about how I'm feeling, and they have a better grasp of medicine than I do! And consequnly we have a relationship of equals. I never make the mistake of treating them as anything less than a highly trained professions, and so far they have all repayed the compliment.
Post M/C I developed a rare condition called Asherman's Syndrome. I saw my GP and told him that my periods hadn't started. He told me that it could be stress. I disagreed (politly), as I'd been stressed in the past and had never missed a period. I also told him that I was getting ovulation pain, and period pains once a moth, but no bleeding. Could I have adhesions in the uterus, I asked him. Yes you could, he said, and refered me.
We both worked towards the dx in an attitude of mutual respect.
Had I gone in demanding a blood test and a hysterosalpingiogram (sp??? not a doc) he might have been thrown on the back foot a little, and being human, might have been somewhat defensive.
making negative comments are seldom that productive.
