Did it happen again? Did you get checked out already?
I'm not a healthcare professional, I am but a simple medic but I know some doctors so I can consult them if needed.
Can you expand on the seizures?
Did you pass out? Do you know for how long?
Did you feel anything special before or after the seizure?
Numbness, chest pain, head ache, specific weakness...
How much time passed until the feeling wore off?
Did the seizures happen because of any special reason?
Did you have any more seizures since then? How much?
In any case I advice you to get checked on by a doctor if it's possible, even if you didn't get any more seizures since the time you wrote this message.
If by any reason you don't want to, then I'll be happy to get your answers on my questions so we could try to figure out what we are dealing with:)
