cher53, you don't have to go for further tests if you choose not to.
My blood pressure is borderline high too, or it was last time I was measuring it regularly so as to get an average reading for my GP (about a year ago, I think). GP talked about blood pressure medication and so on.
Then I said: I've never smoked; I've never been overweight; there is no family history of heart disease; I must be low risk. GP agreed.
So, I continued, reducing my already low risk of health complications caused by borderline high blood pressure by a little bit more to make it a very slightly lower low risk, is a bit pointless. Besides, as you know, I'm in pain all the time. Won't that push up my blood pressure?
GP hasn't said another word about it.
I'm not advising you, just telling a story. I think we overtreat risk. I'm all for treating actuall health problems and for vaccinations to prevent diseases, but reducing small risks to slightly smaller risks seems a bit daft to me.
Costly too.
