frustrated mom,
There may be more history of Migraine in your family than you think. Most of the time, if people look back, they find relatives with "sick headaches" or "sinus headaches" that were actually Migraines.
There are several types of Migraines and many different symptoms. It is indeed quite possible to have a Migraine without any headache. The headache is just one possible symptom. Take a look at Anatomy of a Migraine and Acephalgic or Silent Migraine - The Basics.
All of your symptoms could be Migraine, but we cannot diagnose or confirm a diagnosis online.
Did the neurologist you saw suggest any treatment? There are effective treatments, both to reduce the number of Migraines and to treat the Migraines we get. If your neurologist isn't able to help you, seek care from a Migraine specialist. Read Migraine and Headache Specialists - What's So Special? then, if you need help finding a specialist, see our listing of Patient Recommended Migraine and Headache Specialists.
Good luck,
Teri
