If you get heartburn, you know the feeling well: a slight hiccup and then a burning sensation in your chest and throat. It could’ve been something you ate, particularly any spicy, fatty, or acidic foods: the jalapeño nachos with extra salsa or the deep fried onion rings maybe weren’t the best idea. Or perhaps you have gastroesophageal reflux disease, which is a chronic condition. Whatever caused it, you’ve now got discomfort and an upset stomach.
