I get migraines all of the time. I wish I knew what caused them. 
There isnt any real cause to migraines, they are just intense headaches that are severely debilitating but they seem to be genetic
That would make sense. My mom gets them alot. Drinking lots of water seems to help. 
Yea a lot of migraines are just headaches but more intense and severe though a lot of headaches are simply from being dehydrated
