My 14 yo daughter has had very bad headaches two three times a week for over 2 years. There are no specific triggers or patterns and no warning. They are always in the same place and can last anything from 2-5 hours. Painkillers don't work. She doesn't have a sensitivity to light, nausea or auras before or during these headaches. After 2 years of being fobbed off and told these are part of growing up, we are finally getting an MRI scan and listened to. Can anyone suggest any questions I should ask and what it could possibly be. They don't seem to think it's migraines.
