How dermatology became the 'it' job in medicine

I had a similar experience - The dermatologist that I used to see moved to a new city and I needed to see one urgently for eczema. Primarily, I needed an RX.

For at least two months, no appointments were available with any derm in my network, so I immediately set up a telehealth appointment with one in another state, explained the condition, and got an RX on the same day.
