If you think you have high blood pressure, see a doctor. Don't fool around with trying to control it on your own!
It can indicate a serious medical problem that could cause stroke, or heart attack.
I've had HBP for 40 years, been on medication that long. My current BP is about 125 over 70, and I want to keep it there.
Particularly since I had angioplasty a month ago for 3 blocked arteries in my heart.

Get thee to thy physician!
