Telling someone not to worry about something, particularly from a position of authority, when the chances are (again, math) that it's not serious seems a charity. "You're fine, and come back in a week/month if it persists. But, stop worrying." is a fair approach. Nobody wants someone else to worry unnecessarily. It's pointless.
> The persistent conviction that one is never or is likely to never become ill, often involving blatant disregard for emergent symptoms, and persisting despite reassurance and medical evidence to the contrary.

But there's a variant of that too that will beg you not to call an ambulance for them (either if they're conscious or via a bracelet or something); in the US especially, medical costs are a deterrent for seeking help. It's a thing in my more socialist country (Netherlands) too, where there's a €385 a year deductible for many health care expenses; a lot of people cannot afford that, and they can barely or not at all afford the €144 a month for the base insurance (average rate, although people get a rated government subsidy if their income is below a certain threshold)
Once I went for a dip in the spa and when I finished, decided to stretch out on the bare ground for a bit to relax (chaise lounges were removed during pandemic)
A neighbor lady immediately began shouting at me and started to call 911. I had to prove I wasn't dead!
Another time I sort of freaked out at a bus stop and laid face down on the sidewalk. Drew a huge crowd and while I refused to move, the ambulance rolled up. There was nothing physically wrong with me but I was transported anyway, just to peel me off the public right of way.
I visited a little pharmacy-based clinic for blood-pressure monitoring and they took two cuff measurements. The charge nurse said it's alarmingly high and she's required to call 911. So I found myself fending off a cadre of EMTs who insisted I needed to go; they put me on the phone with the ER doc who read me the entire risk profile before the ambulance could be dismissed. I calmly informed them that their presence was extremely distressing to me and the sooner they went away, the sooner my diastolic would readjust.
I've walked into Urgent Care and ER 3 times with cardiovascular concerns and each time the outcome was like, "yeah, keep an eye on that for us."
They can bill the patient for hijinks too. Perhaps the general public has hypochondria and enjoys transforming minor annoyances into state-sponsored crises.
If you're conscious and stable, an EMT visit will culminate with the $64,000 Question: "Do You Want to Go to the Hospital?" Well you're the pros; is it necessary or not? Call my insurance or something.
