No, there isn't any such thing as a "sinus Migraine." Nancy gave you a good link about Migraines being mistaken for sinus headaches.   You really need to see your doctor for diagnosis if you haven't already. One of the most important things with any form of "headache" is to get an accurate diagnosis. To simplify matters and make it easier for people to get information and treatment, doctors usually go by the gold standard for diagnosis, the International Headache Society's International Classification of Headache Disorders, 2nd Edition (ICHD-II). You can read more about this in The Type of Migraine Does Matter.   How many days a week do you take something to relieve these headaches? Taking Migraine abortive meds such as the triptans or ergotamines or any kind of pain medication -- prescription or over-the-counter -- more than two or three days a week can make matters worse by causing medication overuse headache (MOH), aka rebound. See Medication Overuse Headache - When the Remedy Backfires for more information on this.   I hope this helps, Teri
