Cluster headaches and medication overuse headaches (formerly known as rebound headaches) are also relatively common. Sinus headaches are much rarer, he says, but not as rare as more troubling syndromes Cowan has treated, including SUNCT headaches, in which patients experience brief stabbing pains as many as hundreds of times a day that require IV medication to treat.
