In my second paragraph I pointed out that this probably isn’t bias, this is Occam’s Razor. If the razor cuts against you, it’s your problem as a patient to fight back.

Is that fair? No. Does a medical professional have an obligation to take a patient seriously? Yes. But I bet busy physicians have an hard time avoiding being biased by direct experience with unreliable patients: drug seekers, people with mental health issues, people who want the drug they saw on Fox News ads, etc.
