Migraines are a common ailment that affects a significant proportion of the population, and allergies can trigger them. Allergy symptoms such as nasal congestion can irritate the trigeminal nerve and trigger migraine attacks. Therefore, patients who suffer from migraines should be screened for allergies, which could then be treated. While allergens are not responsible for triggering migraines, they cause symptoms that can lead to migraines. Hence, treating the symptoms of allergy can potentially improve outcomes for patients with migraines. Seasonal allergens such as pollen, mold, and pet dander can inflame the sinuses and trigger migraines because of the proximity of the eyes and sinuses to the nerves that get triggered in migraines. Allergic reactions can cause runny nose, congestion, and postnasal drip, among other symptoms. Furthermore, allergies cause inflammation that could increase migraine frequency. The key to treating both allergy and migraine is to avoid dehydration and inflammation in the sinuses. Therefore, allergists can help by doing allergy testing and treating the underlying allergies. Collaboration with ENT, allergists, and migraine specialists is important in treating migraine related to allergies. Finally, it is important to create an allergen-free atmosphere at home and to have a HEPA filter, change air filters regularly, and use a dehumidifier to prevent more growth.
