I had upper endoscopy it showed hital hernia, irregular zline,tongues in esophagus,&gastritis. I have had heartburn my whole life. I'm 56.I have crohns and take 6mp& azuldifine. My endoscopy is negative, but I'm worried should I have another one or a follow up? Could barretts esophagus be there and was hiding under hital hernia?
