Migraine Headaches

my hubby used to get really bad migraines when he was a teenager and into his mid twenties.his dad told me one time they were all watching t.v. in the living room and my hubby walked out of the room holding his head. Ten minutes later his mom found him curled up in the fetal position in their front yard and there was a horrible storm outside. It's like he goes into a trance the pain is so bad and he doesn't know who he is or where he is or anything. He hasn't had a bad migraine like that in a while. He had one when he was guarding the SuperDome down in N.O. right after Hurricane Katrina hit but otherwise he has been fine.
