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.
Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to something in the environment that usually causes little or no problem in most people. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, runny nose, shortness of breath, or swelling. Food intolerances and food poisoning are separate conditions.
