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 on a routine visit. this is especially important if you have a close relative who has hypertension or embodies risk factors for it. if your blood pressure is extremely high you may have unusually strong headaches chest pain and heart failure (especially difficulty breathing and poor exercise tolerance). if you have any of these symptoms seek treatment immediately.
