Gas pain in the chest can be a symptom of a variety of medical conditions. It can be caused by indigestion, gas in the intestines, or digestive disorders such as irritable bowel syndrome or GERD. It can also be caused by heart problems such as angina or a heart attack. Treatment will depend on the underlying cause, and can include medications, dietary changes, or lifestyle modifications. In some cases, lifestyle changes and over-the-counter medications can help relieve the pain of gas in the chest. If the chest pain is severe, or is accompanied by other symptoms such as shortness of breath or sweating, medical attention should be sought immediately.
