Quick answer
Usually not. Most people with high blood pressure feel completely fine, which is why it's called the "silent killer." The only way to know is to measure it.Most people feel nothing
Nearly half of U.S. adults have high blood pressure, and many don't know it. It can quietly damage blood vessels for years before any symptom.
Headaches
Everyday headaches usually aren't caused by blood pressure. A sudden, severe headache with a very high reading (180/120 or more) is an emergency sign.
Dizziness, nosebleeds, flushed face
These aren't reliable signs of high blood pressure. Dizziness can be a side effect of some blood pressure medicines, so mention it to your doctor.
What it can do over time
Untreated, it raises the risk of heart attack, stroke, heart failure, kidney disease, vision loss and memory problems.
What to do
Measure at home or at a pharmacy, and share repeated readings of 130/80 or higher with your doctor.
