Acid reflux is painful. Food and acid splash into the esophagus and cause belching, heartburn and, in some severe cases, chest pains. Some individuals have experienced pain so intense they thought they were having a heart attack. If a person experiences acid reflux on a regular basis, the acids will irritate the esophagus, which may advance to scarring, ulceration, swelling or hemorrhaging. What is the risk of acid reflux? Many experts agree, if acid reflux persists, it may lead to esophageal cancer.
