Allergy migraines can be triggered by an allergic reaction to food. With a food allergy, the immune system mistakes a food as harmful and releases substances that can trigger head pain and congestion. Migraines can also be caused by seasonal allergies or hay fever. Seasonal allergies can cause the sinuses to swell, which can trigger migraines. Allergy migraines can also be caused by common indoor allergens like urine, dried skin, pet dander, cockroach particles, mold and dust mite droppings.
