Well, I'm glad to hear that the brain scan came out ok. There are many reasons why a person can suffer from migraine headaches. The pain is probably what is causing her to scream and feel unhappy. Migraines can be caused from a food allergy or even stress. Has she had a lot of stress lately? Does it occur after eating a certain food? I get horrible headaches and dizziness when I smell perfume. PMS in women can also cause horrible migraines. Have her take notice on when these migraines happen and mark down the dates to see if there is a pattern.

I hope this helps and she feels better soon!

She'd no stress around these days. I did tell her to take written notes but there is something that I forgot to mention. She experiences Deja Vu's almost 3-4 times a week. I told her to write down her deja vu's time, type duration and foods taken before them. I am looking forward to have an aggregate of monthly report and analyze it to reach a conclusion of the possible allergies/associations etc. She can clearly discriminate Migraines from these special headaches. Which means she does have migraines but the Headache is something else. I am pretty sure a deep chronic study is required to find the proper solution.

I agree. I hope your sisters finds some answers soon so she can feel better. Keep us posted!
