hi, I have a question,my mother had surgery in february 8 of this year,after that surgery everythin was ok she open her eyes and made some movement,her head was not shaking or anything,surgeon put her on keppra to prevent any seizure,but before puttin her on that medication he check her brain to see if she gets seizure,there were no sign of seizure so he gave her that medication and after that like in two days she end up having tremors in her head in other word head shaking,what could it gone wrong if they didnt found no sign of seizure.
