Headaches with Allergies It is not uncommon for headaches to occur with allergies particularly where the allergy involves the upper respiratory tract (nose, sinuses and throat). Three types of a headache are often mentioned in association with allergies. This includes: Sinus headaches Migraines Cluster headaches Sometimes other conditions that accompany a headache may be mistaken for an allergy.
