Hi michele. It is so hard to wait for the doctor appointment after an eeg. We had to do that with our son, also.
I do not know what happened during the eeg, but it sounds like you feel you had a seizure. Did the tech say this or just what you recall of things happening? (techs are not supposed to tell you anything.) it is best to wait it out and hear what the doctor says is going on.
I know it is so touch....Migraines can go along with seizures or they can be totally separate. You can go to emedicine and to neurology there. They have great articles on seizures and migraine variants also!
Best wishes for a good appointment! Hoping he has help for you!
