First, "migraine" is an abused term today that is commonly used to just mean a really bad headache, even by doctors but it is way more than that. I started getting migraines when I was 5 y.o. and would bang my head against the wall because that pain would lessen or take my focus off the pain in my brain and eyeballs. The key markers of migraine to distinguish it from other types of headaches is sensitivity to light and sound, nausea/vomiting and visual disturbance called migraine aura. So I am happy to advise but what are your symptoms?

Second, vertigo (which I don't have) can have a number of causes but the most common is Meniere's disease which can be cured or controlled.

That said the headaches and the dizzyness may be related or unrelated and step one is to make that determination.
