2. PAIN IN OTHER AREAS OF THE BODY.
Heart attack pain can occur in places other than the chest, like the back, shoulders, arms, neck or jaw. According to Cleveland Clinic, when there’s a problem in the heart, such as a blocked artery, it can trigger the nerves in your heart to give a signal that something is wrong, and you’ll feel pain. Considering the vagus nerve is connected to not only the heart, but also the brain, chest, abdomen, and neck, you may feel those pain signals in other areas of the body aside from the heart region.

3. DIZZINESS.
Many things can make you dizzy: not drinking enough water, skipping lunch, or standing up too fast. But dizziness or lightheadedness coupled with chest pain and shortness of breath may signify a decrease in blood volume and a drop in blood pressure, which means a heart attack could be on it’s way.
