Thank you for your query.
It is very common to have Todd's paralysis
following a seizure
. It is not clear from your query if the pain in the abdomen is preceding the seizure or following the seizure. Pain preceding the seizure can be a premonition of the impending seizure. Post seizure pain can be due to over-activity of the muscles during a seizure. Nevertheless, it is better to get the child examined and investigated to rule out other possible causes.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
