Why with cardiac heartburn will I also experience heart pain?

The discomfort of heartburn is actually not originating in or around the heart. Heartburn refers to the burning feeling in the chest caused by acid reflux from the stomach into the esophagus. Sometimes there can also be a squeezing or pressure sensation from heartburn when there is associated spasm of the esophagus. This can make it difficult to differentiate from angina, chest pain due to decreased blood flow to a portion of the heart. It’s always best to call for immediate medical advice when a person is unsure about the cause of chest pain.
