Chele,

A thunderclap headache should always be very carefully evaluated as they can indicate a stroke. Hopefully, your doctor ruled that out. I've not read anything in the literature about a thunderclap headache resulting in daily Migraine.

One of the most important things 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). Under ICHD-II, there is no diagnosis of "occipital Migraine." We do see it used, but doctors use it differently, so it really doesn't tell anyone what type of Migraine you actually have. You can read more about this in The Type of Migraine Does Matter.

If your doctor isn't able to help you, it may well be time to consult a Migraine and headache specialist. It's important to note that neurologists aren't necessarily Migraine and headache specialists. Take a look at the article Migraine and Headache Specialists - What's So Special? If you need help finding a Migraine specialist, check our listing of Patient Recommended Migraine and Headache Specialists.

Good luck,

Teri
