Esophagitis

Esophagitis is when there's a boo-boo in the little tube called the esophagus that connects your mouth to your stomach. When you eat and drink, the food and drink goes down this tube. But sometimes, things like acid from your tummy or even some medicines can irritate or hurt the esophagus. It can make it feel like you have a bellyache and it might hurt when you swallow food or drink. But don't worry, the booboo can go away with special medicines and eating more gentle foods for a little while.
