Usually doctors still operate by the book. All symptoms and deductions have to make sense in the "context" of the "book," if the book doesn't mention it, the doctor doesn't proceed any further.

For example, I slept on my bed with a heater blasting onto my face. Next day I developed sudden onset dry eye. Literally from eyes that had zero issues to dry eye. I think the heater was the causative agent, but the medical literature is blank on this, so the doctor is clueless as well. In fact the doctor literally ignores the fact that I had a heater blasting my eyes all night. I came in to the eye doctor and he assumed that my dry eye developed over a long time when in actually I "caught" it three days ago.

One perspective of this is that the patient is biased and assigning causative attributes to something that only happens to correlate with an outcome. Therefore all patient descriptions must be cut through and ignored if it's not relevant to the problem. It's largely true but I think doctors bias themselves towards this predisposition a little too much and dismiss many things that are actually important.

Either way though, if it's not in "the book" then treatment for it doesn't exist in any scientific form yet, so the doctor can't help you anyway.
