Migraine attacks are reported by many patients as headaches and many are unable to differentiate it from other headaches.

However, a migraine headache is a special type of headache. Classically, the single most characteristic feature of migraine is episodic headache associated with accompanying symptoms like vomiting, blurring of vision etc. Episodic headaches means that they can occur anywhere from once or twice a year to 1-4 times a month but in between, there are prolonged pain free intervals. However, occasionally some patients may get headaches more frequently, almost daily. The headache is usually felt on the one part of the head.
