i am 17 and i don't know why i am having seizures. I have had seizures for two years. Shaking, biting my toungue, and sometimes just blank stares, or passing out. I have been to many doctors, but one neurologist. I have had many tests done, but no one can tell me the exact reason why i am having seizures. I am taking a medication called topomax at first i was taking it for chronic migraine, because i also suffer from migraines everyday. I had a seizure while taking topomax and now have to increase the dosge again. they say i have seizures when im sick or stressed. i guess you would call this stress endused seizures, but it doesn't only happen when im stressed out. or sick anymore. i dont know why im having seziures i hope the doctors are doing all they can. my grandma had epilepsy but they couldnt control her seizures either, ive been tested for almost everything but nothing has come back abnormal except the fact that no one know what is wrong with me. can anyone help? is anyone going through what im going through?
