I live in Los Angeles and I am not sure about all categories of doctors but I am wondering if there is a shortage of dermatologists. Recently I was traveling and I felt a large bump on the top of my head. I had it for several weeks but someone noticed it was really red and it was itching a lot. I was concerned so I called quite a few dermatologists in Los Angeles so that I could have an appointment when I came back. Each doctor I called said they could get an appointment for me in about 2 months. Even the physician’s assistants were busy except for one. I called doctors mostly that I had seen previously so I was not a new patient in every case.
I thought I might have cancer so obviously, I wanted to see someone right away. I told the office staff too and they told me in a very business-like fashion that there were NO APPOINTMENTS unless there was a cancellation. I decided to go to urgent care while I was traveling. I was diagnosed with cellulitis and given antibiotics. I did finally find a doctor in Los Angeles, probably because all the reviews were terrible.
When I got back to L.A., I saw the one dermatologist who was free and she said I had a birthmark on my head. She said I was misdiagnosed and to stop the antibiotics immediately. So is that the health care we have and are there very few dermatologists in L.A. who are free? I have excellent insurance, it is a PPO. Or maybe it is not lucrative to see patients for silly things like a birthmark? On all the websites I visited, the main focus was cosmetic dermatology and how you could be beautiful with Botox, lasers, peels, injections, fat reduction, and special lotion only offered by the office. I guess beauty is more lucrative, especially since it is cash only (or credit card) but not paid for by insurance.

Try having an HMO. They will hang up on you.
See aamc.org:
A new AAMC study projects a shortfall of up to 139,000 physicians by 2033. Among the factors: older patients and retiring doctors.
Even as the nation’s health care workforce combats the spread and lethality of COVID-19, a report from the Association of American Medical Colleges (AAMC) projects that the United States will face a shortage of between 54,100 and 139,000 physicians by 2033.
