Chest pain caused by gas usually comes on after eating a heavy meal of oily and spicy foods. It feels like a burning sensation that extends from the upper abdomen to the chest, according to Mayo Clinic. There is little or no sweating, shortness of breath or dizziness.
Gas pain in the chest, or heartburn, typically occurs when a person lies down immediately after eating a heavy meal. When the sphincter in the lower esophagus relaxes and opens up, stomach acids flow upward into the esophagus. This causes a burning pain to radiate from the upper abdomen, through the chest and up to the neck, according to the Mayo Clinic. It can also cause a foul or sour taste in the mouth.
Pain caused by gall bladder dysfunction or by a heart attack can sometimes feel like gas pain, but it usually causes additional symptoms, according to Mayo Clinic. Gall bladder disease pain is accompanied by nausea and discomfort that radiates to the shoulders and arms. Pain caused by a heart attack can begin mildly and increase gradually in intensity. It is felt as a crushing or squeezing pain in the center of the chest that radiates to the shoulders, arms and jaw.
