Chronic cough and even chest pain can be caused by acid reflux. This can be difficult to diagnose because the symptoms are often not associated with classic symptoms of acid reflux, such as heartburn. [Editor's note: If you're experiencing chest pain, it's important to talk to your doctor immediately about whether heart conditions could be causing the symptoms you're experiencing. See common heart attack symptoms here.]
Frequently, cough and chest pain related to acid reflux require double doses of acid-reducing agents for longer periods of time than is typically required to treat heartburn. If you are experiencing a chronic cough or chest pain, check with your doctor immediately.
