Migraine is often confused with headaches and usually starts with a throbbing headache centered above the eye or begins at the back of the head and spreads to one side. Migraine is often accompanied by nausia and vomiting. Attacks can be triggered by perfume, cigarette smoke and bright lights. Sometimes excessive dairy products in the diet is the cause. One of the most causes is eating and drinking chocolate, caffeine and drinking red wine.
