If you've had regular checkups, not just one, there would be a pattern of high BP and the doc unless you have a bad doc would mention it. But if you're not having any symptoms of high BP and the doc isn't expressing any concern and you're still compulsively checking your BP that suggests an anxiety problem. Most people, even most anxious people, don't obsessively check their BP. The only people who should ever do that are people who have been told to do that by their docs. So what are you doing to treat your anxiety problem? Do you have a therapist?
