Usually ge reflux: Heartburn or gastroesophageal reflux is the most common causse of chest pain, often mimicikng cardiac pain. You should have gi workup having excuded cardicac etiology. I noted you are on aciphex (rabeprazole). Sometimes if refux persists without relief other issues such as gastritis, slow stomach emptying may contribute. Musculoskeletal issues are sometime to blame with inflammation or trauma.
