What happens when you have a heart attack?

If experiencing a heart attack, you may feel a dull thud or squeezing of the chest and pain shooting up and down in one or both arms because the blockage of the artery is causing blood flow to back up, and you feel the pressure. Shortness of breath is common when having a heart attack because your lungs aren’t receiving the blood they need. You might also experience lower abdomen discomfort and sharp pains. You may also experience a burning sensation around your chest, arms, jaw and neck, or even nausea and/or vomiting. These symptoms occur because many of the nerve pathways that serve the heart also serve the abdominal region. During a heart attack, muscles don’t receive the oxygenated blood they need, so they begin to send out pain signals.
