Goalposts seem to vary by country and over time.
But I will - at the very least - believe I have a condition when I have troubling symptoms of a condition, that are making my life a misery, regardless of what the goalposts say.
So if I'm going to the loo five times a night; if I have constant raging thrush/crotch itching for first time in my life (and scalp itching and general ultra-dry skin problems with hands, feet etc); if my extremities (esp feet) are not feeling at all normal; if I'm feeling so exhausted that it's an effort just to get out of bed (I'm normally fit and sporty), for months on end; if tiny spots and cuts that normally take 2 or 3 days to heal are taking five or six WEEKS, leaving strange dark stains on my skin (including on my face :-( ); if my blood pressure has shot up for no apparent reason; if I'm having trouble doing my work properly because I just can't seem to focus properly with my almost new and very expensive top-of-the-range varifocals; and if patterns of darkened skin starting to appear, on my neck ... If when I'm 54 but I feel like 94 and ready to drop my clogs...
If I have this bunch of symptoms, I expect someone to say 'we think you've got x; and we/you can to y'. I don't expect someone to say 'you're completely normal and don't have anything; go away'.
What I find troubling is that countries appear to determine goalposts not necessarily on any medical basis, or on the basis of long-term costs/benefits to the individual and to society; but on the basis of the short-term healthcare bill i.e. on the basis of wanting to avoid short-term costs, but ignoring the long-term impact on both citizen and country.
