Hi, I'm 40, very fit and healthy, I do lots of sport and eat fruit and vegetables and am not over weight. I have suddenly found that I have high blood pressure. I'm going to see my GP on Monday about it, but could do with some advice. Right now my blood pressure is 175/90. Am I supposed to go about my usual business or should I go and lie down? I have no other symptoms. Having looked on google I'm imagining that I might have some kidney problems or something. My blood pressure was even higher on Thursday and I was given a CT scan to see if I had had a stroke but it was normal. Any advice greatfully received. I'm planning to go running in the morning - should I still do this?
