Just because you get a headache doesn’t mean that you have high blood pressure. Headaches CAN be an indication of very high blood pressure, but more often that not, a headache is just a headache. Take an aspirin or a Tylenol and move on. Hypertension isn’t called “the silent killer” for no reason. There are no symptoms that you or anybody else would recognize as symptoms of high blood pressure.
If you or someone you love is having a SEVERE headache, blurred vision, and nausea all at the same time, you should without any hesitation, get to a doctor or an emergency room. Those symptoms could indicate a blood pressure that is high enough to cause a heart attack or a stroke, or worse.
However, most people discover that their blood pressure is elevated in one of two ways: (1) they go to their doctor for some other problem and the nurse finds the readings high. He or she reports the finding to the doctor, who then reports the finding to the patient; or (2) they wake up in the emergency room after they have had a heart attack or a stroke without having experienced any symptoms at all.
Readings that are 140 (systolic) and 90 (diastolic) indicates hypertension. Now, just having ONE reading at that level is NOT an indication that you have hypertension. Blood pressure fluctuates all the time. Immediately after you have done strenuous exercise, your blood pressure will be higher. If you are suddenly stressed or frightened, your blood pressure will rise.
However, several readings at various times that are consistently as high as 140/90 or higher do indicate that you have high blood pressure — with or without a headache.
