Everyone's blood pressures rise and fall continuously, - exactly as your hands on the driving wheel never stay still, -even if you're driving along a 500-mile straight road in Nevada. That's how the system works and is called "hunting". In your brother's case, you don't say how much they rise and fall. -If it's excessive, then of course the doctors will be concerned and will need time to find out the cause, so won't be able to tell you much at this stage. It may simply be distress about the unknown cause of his chest pains that is causing his pressures to rise and fall. -Blood pressures respond to stress, both physical and mental. Be patient, -there's nothing you can do to assist yet and as soon as they find what (if any) is the problem, they'll discuss it with you. It may take some complex testing, and you wouldn't want to be misled at this stage, I'm sure. Then again, it may be something quite simple, easily put right, and not even a problem. But do bear in mind that if his B/P's DIDN'T go up and down, continuously, then he'd be in trouble, and different from every other human being alive. Hope this helps. -good wishes.
