Dizziness
Though most heart attacks don’t make you suddenly lose consciousness, they can reduce or cut off blood flow that brings oxygen to the heart and brain, which may cause you to feel light-headed.
Upper body pain
Our heart doesn’t have many nerve endings, so it sometimes shares a pathway with nerves to other body parts, causing pain to radiate to the back, shoulders, arms, neck or jaw. Some women say it feels as if an elephant is sitting on their back.
