Hi, The information regarding your daughter s history is quite incomplete. No seizures for 3 years means did she have a seizure disorder before and what was the disorder and medications she was on at that time. It s difficult to comment without knowing the complete history. I suggest you to visit your pediatrician/ pediatric neurologist with all the previous documents for further evaluation of your daughter s headache. I hope the above information helps. Thanks for writing into healthcaremagic.
