I sometimes regret that I told my doctor that I suffer from anxiety and panic attacks. After it was written down in my patient journal, I have had trouble talking to doctors about non-anxiety related topics.
An example was last summer where I had a serious case of chickenpox.

I called my doctor, who said that "when you are stressed, you can sometimes get rashes", and when it got worse I called the emergency number for the hospital. At first they took me seriously, but then... "Ah, I see you suffer from panic attacks?", and then the whole conversation changed, and I got advices like "Just take slow and deep breathes" etc.

It was not until after a week that my doctor finally decided to see me, and immediately saw that I had chickenpox.

Ir really bothers me that people think that when you have anxiety, all kinds of medical emergencies are just your imagination.
