<s>[INST] How Do I Know If I Have High Blood Pressure? [/INST] High blood pressure often doesn't have any symptoms, so you usually don't feel it. For that reason, hypertension is usually diagnosed by a health care professional during a routine checkup. If you have a close relative with hypertension, or other risk factors, it is especially important to pay attention to your blood pressure reading. In order to diagnose high blood pressure, your doctor will check your blood pressure with a blood pressure cuff. It's important to pay attention to both the higher (systolic) and the lower (diastolic) numbers in your blood pressure readings. If your blood pressure is extremely high, you may have unusually strong headaches, chest pain, difficulty breathing, or poor exercise tolerance. If you have any of these symptoms, seek an evaluation promptly. Source: webMD. Link: https://www.webmd.com/hypertension-high-blood-pressure/hypertension-frequently-asked-questions .
