You’re basically correct, but with a caveat or two. Disease tend to boil down to only a few basic etiologies: cancers = improperly dividing cells, autoimmune = body attacking itself, etc. There’s a LOT of specific diseases out there, and the mind is finite. We discreetly go around the corner to check references (hopefully not Google) on our phones ALL THE TIME in the medical community, MDs to RNs. We might not know your exact symptoms off the top of our head, but even that varies from patient to patient within a single diagnosis. That’s part of why a face to face consult is so important, and assuming that a doctor asking questions about your condition is ignorance is probably (usually) wrong… Also, I had a patient last week explain to me that high-voltage power lines cause cancer, and as a survivor of breast cancer, she was more knowledgeable about this than I was, so… It goes both ways sometimes.
