Most "Migraines" Are Actually Sinus Headaches
True sinus headaches are relatively rare and almost always accompany a sinus infection.
It can be easy to confuse the two headache types because migraines sometimes cause sinus symptoms, such as pain high in the cheeks and a stuffy or runny nose. But if those symptoms come with moderate to severe pain, nausea, and/or sensitivity to light, you probably have a migraine.
It's important to know which type of headache you have to get the right treatment.
