Many people with chest pain fear a heart attack. However, there are many possible causes of chest pain. Some causes are not dangerous to your health, while other causes are serious and, in some cases, life-threatening.
Any organ or tissue in your chest can be the source of pain, including your heart, lungs, esophagus, muscles, ribs, tendons, or nerves. Pain may also spread to the chest from the neck, abdomen, and back.
