I don't know who needs to hear this but you CAN and SHOULD terminate a doctor patient relationship at any time if you are dissatisfied with their service or uncomfortable in anyway.
I stopped seeing an allergist who said "Get rid of the cats and put that dog outside" as response to a description of my allergies, without ever giving me an allergy test.
(My next allergist actually did his due diligence and discovered that half the reason I couldn't breathe was because I had allergic scar tissue in my sinuses).
I stopped seeing a gastroenterologist when he didn't make an effort to learn my name, familiarize himself with the treatments I had tried that did not work, or read the list of known medicine allergies attached to my chart.
(He asked me when my last colonoscopy was LESS THAN 48HRS AFTER HE PERFORMED IT and re-prescribed me a medication that had hospitalized me)
I stopped seeing a certain psychologist because, despite my complaints about the damage that it was doing to my stomach lining, he wasn't willing to switch my meds in favor of something less destructive.
(My next psychiatrist agreed to see me WEEKLY while she weaned me off the meds he had put me on, and spent months checking in with me and tweaking my medications until we found a medication that helped my depression sufficiently without killing my stomach.)
Don't pay to see doctors who refuse to run tests!
Don't pay to see doctors whose bedside manner makes you uncomfortable.
Don't pay to see doctors who ignore your complaints about medications.
re: your tags, yes bad doctors are dangerous. as a healthcare professional, i think you should absolutely be able to pick the physician you see, hopefully someone who listens to you and is able to evaluate your needs and doesn’t ignore what you say.
as someone on their way to becoming a primary health provider, i second this post 100%.
don’t pay to see bad doctors. pay to see someone who will listen to you and address your needs.
also like don't be afraid to fire your doctor and speak up when they do something you aren't okay with
