Seriously, my comment was not simply to amuse but educate and urge. Go and get your blood pressure taken , if you are the person you are concerned about. Its cheap, simple and accurate.
Symptoms like redness, swelling and nosebleeds can also occur with so many other problems they could not all be listed. I mean starting with nose picking, how many more causes of nosebleeds can we come up with?.....a hundred without pausing.
What anyone who thinks they have high blood pressure can do is go get your blood pressure taken.
Whatever you do... don't assume you have high blood pressure because of having something like facial redness and then do something as stupid as self prescribing yourself some blood pressure medicine you buy off the internet.
