What Does It Mean When You Can Feel A Pulse In Your Forehead?

A pulse is due to blood flow. If on forehead, can either be a headache, or sometimes anger, or frustration as blood will rush to area. Same with fear, blood seems to empty from stomach area and go to other places. Blood flow is interesting. You can eliminate some headaches where blood flow is high just by pressing on that area, to slow the flood of blood rushing to brain

It might also be a migraine, which is basically like a headache but worse.
