Problem with High Blood Pressure is that you might not have any symptoms at all..... Best way to tell is to get a home monitor, there are many out there that aren't too expensive..... Do a search, but some physical signs I can think of are Redish face, or flushed looking..... If you can feel your pulse in your temples beating, even if your not touching them, that's a sign..... You can even get blood in your stool.... There are tons, and everyone is different...... If youre really concerned, I'd get some type of device to measure it..... They have like digital cuffs where you push one button, and it takes your pressure for ya..... No need to know how to use a cuff.... Do a search...
