Thanks for that Musicaltheatremum. My feeling has been there would be better protocols for dealing with this under the NHS than here, and I'm glad someone agrees I'm not just being paranoid, though I am partially relieved the private gp was reassured.
We're not back in the UK until the 6th Jan. There are also added complications there because we moved recently a year ago and DP still hasn't actually registered with our local GP. If he gets an appointment then, would they still refer him? Would any blood tests be too late?
I remain worried because he has a family history of extremely high blood pressure, has been under a lot of stress and from a BMI point of view is overweight (he carries it well, but I suppose that doesn't make a difference as far as health impacts go).
Also stressed because upon thinking about it further I've linked this with the fact that during the year I was woken up twice because he basically stopped breathing in his sleep. It didn't last long, but totally freaked me out, and seemed very much like sleep apnea. He also didn't go to the doctor for that and it seemed to have stopped, but I now realise that may put him at a higher risk of stroke-related issues.
If he goes back to the GP and says something like, in August I definitely had symptoms of sleep apnea, and two weeks ago my eyesight went blurry in one eye for half an hour but I'm fine now: will they look into it? Can they look into it? Will it be too late after the fact for any tests?
He has said, after both these occurrences, that all a doctor would do is tell him to lose weight, which he knows he needs to do, and that he'll just do that instead. But I'm not convinced that's right.
