What does it mean when your chest burns?

A burning sensation in the chest can be caused by various factors, including heartburn, which is due to acid reflux irritating the esophagus. It may also indicate more serious conditions, such as angina or a heart attack, especially if accompanied by other symptoms like shortness of breath or pain radiating to the arms or jaw. Stress and anxiety can also contribute to chest discomfort. It's essential to seek medical attention if the burning sensation is severe or persistent.
