If you’re allergic to things you eat or drink, your body will react if it comes across them. Fish, nuts, and dairy are common triggers. This may inflame your face within minutes, especially around your lips and eyes, as well as your tongue and the roof of the mouth. You may also feel light-headed, nauseated, and itchy on your skin or inside your ears, mouth, or throat. Call 911 and use an epinephrine pen if you were prescribed one.
