Having dry cough and chest tightess mostly with movement i have esophagitis can this cause this problem? , had ekg last week it was ok

Yes.: If the esophagitis is due to reflux of acid from the stomach, it is quite likely to be associated with both chest pain and a persistent cough. It merits a careful assessment to confirm this and is readily treatable with anti-acid medications such as the proton pump inhibitors and the local tissue-coating medication, Carafate (sucralfate).
