My favorite was a doctor who told two separate people in my wife's family to apply tiger balm to the affected area until the pain goes away. After a second diagnosis, the first issue turned out to be an issue with the growth plate in their wrist, and the second issue was a broken leg. Both required surgery.

Doing just about anything that isn't going to the first doctor would have been a more productive use of time. At least a crappy chatbot could tell them to use tiger balm right away without leaving the house.
