Well you can't have it all ways.
When you've got persistent symptoms and Google directs you to the NHS online information and everything you read means you fall into the category of "make a GP appointment" are you supposed to ignore them because it's "probably" nothing?
For 18 months my DM went back and forth to the GP, got put on the Fodmap diet, and her worsening symptoms meant she had to be a squeaky wheel. Actually she had ovarian cancer, which was stage 4 before it was diagnosed essentially by accident. She's dead now.
But because the GP was fixated on IBS, she would have been categorised in the 80% until, well, she wasn't actually.
Either GPs exist to monitor people's health, or they don't - which is it? And how many people will die because we're not supposed to "bother" doctors. I've often been reminded by doctors that I'm not a medical professional and they are, in lofty tones. Well, that's why I'm here mate. And if it's nothing, all well and good, if it's something perhaps we can nip it in the bud with thorough evaluation before it becomes life threatening and a drain on NHS funds.
Sorry but this kind of thing really puts my back up.
If there are a cadre of overly worried well wasting GPs time, then figure out why, because obviously they need some kind of help too. Vanishingly few people relish a visit to the doctor as a fun day out in my experience. I know plenty though who have had their symptoms dismissed or have avoided seeking help with really poor outcomes.
