it would be interesting to hear from somebody who is involved in medical practice
No, it really wouldn't.
On the one hand, some such person would - with some justification, as well as self-interest - that this is a watering-down of healthcare.
On the other, another such person appears on the outlets each year, imploring us to not clog up the creaking NHS with trivial ailments.
We've all heard them, including the 999 call for a broken fingernail (which is self-evidently ridiculous), but I recall one on R5L a year or two ago, when a healthcare professional was jokingly dismissing someone who'd presented at A and E, with what eventually turned out to be indigestion (probably in some part due to them having eaten a large supper shortly before).
My, how the doctor and the presenter laughed!
A friend's dad ate a large meal, then went to have a sit down and a bit of a play on his computer.
Shortly afterwards, he clutched his chest, then died of a heart attack.
It was Christmas Day.
