What are the symptoms causes by highblood?

The silent killer. In general, there are no symptoms from high bp, hence its nickname, the silent killer. Many people can tell when their BP goes up quickly and fairly high, by getting a headache, and some may get chest discomfort (usually those with heart disease). Hi-bp damages your heart / brain / kidneys / eyes as a slow process over time. If worried, check your BP and if >140/>90, get treated.
