A humming sound in your ears can be a symptom of high blood pressure.High blood pressure, also known as hypertension, occurs when a person’s blood pressure reaches above 140/90 mmHg or higher. This can be chronic, and while it can be harmless, it can also develop into health issues over time.“If your blood pressure is too high, it puts extra strain on your blood vessels, heart and other organs, such as the brain, kidneys and eyes,” the NHS says. And if left untreated, it can heighten your risk of heart disease, strokes, kidney disease, and more. The NHS advises that “The only way of knowing whether you have high blood pressure is to have a blood pressure test.” So, if you’re concerned about your levels, head to a GP or pharmacy to get your blood pressure measured.In fact, many people don’t even know they have high blood pressure until they measure it.But
