Migraine with blindness, nausia but without headache

I am very upset with the doctor treating my friend.  What started my search is when a doctor said it might be in her head and he was serious.  I'm not a doctor but I would think they would do some kind of process of alimination or at least tell her types of food and or meds that would trigger a migraine.  I am searching for answers for her.  I understand that everyone is different and I am just looking for info to find her the help she needs.  She has had migraines without headache since she was little.  Once a month for as long as she can remember.  She is 25 now.  Once a year she she has a ceasure.  She just had a seasure and it was just 6 months after this time.  She also has nasua but has a problem throwing up and can not even force herself too.  She says that it is like somthing blocks it in her chest.  I'm wondering if all these could be related. She lives in RI and there are no migraine specialists here.  I just read about a clinic called NECH, New England Center of headache but I read that a headache is just a symptom of some migraines (which she does not have, just pain in her eyes nausia and blindness) and a migraine is a disease. Any information would be greatly appreciated.  Thank you
