SF - As you get older it seems, your medical needs slowly escalate and you find yourself more and more in front of medical professionals, at least that’s my experience.
I'm not sure where you reside, but here in my part of the UK, it's near impossible to get to speak to an NHS doctor at the practice I've been at since I was a bairn.
I have not had need to mention blood when I have been lucky enough to get to speak to a Doctor, usually on the phone.
Every 2 years NHS send me a bowel cancer screening kit.
So far so good. The mysterious virus of 'unknown origin' thing did not exactly do any good to the NHS.
