I learned from hard experience always get advice from more than one doctor. Also never trust a doctor.

I once had a throat infection for months and it was getting worse and I worried it would spread to my lungs. My HMO assigned me a young doctor; he refused to prescribe an antibiotic, saying he had to cut down on antibiotics as too many drug resistant germs were evolving due to overuse of antibiotics. The little herd mentality brainwashed little fucker. I went to another doctor. He prescribed an easy round of amoxicillin. It cured the problem within weeks.

Thing is, this was not an isolated issue. In later years multiple times a first doctor was wrong and the second doctor was better. And DEI doctors and many many foreign doctors are flat out incompetent.
