I was eating a piece of blueberry bread and suddenly the right side of my tongue began to swell, my right gland swelled so much that there is a visible "lump" on the outside of my neck, and my ear (eustachian tube) hurts. I am 45 years old, have never had a food allergy to anything, including blueberries, but did have a sinus infection last week which I was treated with Azithromyacin. My concern is because it happened so suddenly while I was eating and doesn't seem to be related to my most recent infection, as all seemed better.
