My 7 y/o daughter was recently diagnosed as Epileptic and from the research that I have done it doesn't sound like Epilepsy to me. Now I don't know the particulars that happened during the "seizure" but I am no expert but from the sounds of the symptoms it sounds as if it is stomach related. I would ask about her seeing a Gastroenterologist.
I WOULD DEFINITELY GET A SECOND OPINION. FROM THE INFORMATON YOU PROVIDED IT SOUNDS LIKE A PARTIAL SEIZURE TO ME.
I'VE HAD EPILEPSY FOR 30 YEARS - SEIZURES, LOBECTOMY, ALL THE MEDS, SO I FEEL CONFIDENT TO SAY THAT A SECOND OPINION IS A MUST.
KEEP A BOOK OF ANY ABNORMAL ACTIVITY YOUR DAUGHTER HAS - - STARRING, SMACKING HER LIPS, ETC. ALSO FIND A PEDIATRIC NEUROLOGIST FOR THE SECOND OPINION.
THE EPILEPSY FOUNDATION CAN REFER YOU TO THE BEST.
