If i've had a partial complex seizure twice in one day and don't have them again. will it ever come back? not diagnosed with seizure disorder. i know i've had two before and had seizures in the past, but never been diagnosed. will it get worse?

If you have previously experienced TRUE epileptic events, odds are at least 60% of having future events. It is very worthwhile to see a neurologist who focuses in area of seizures and epilepsy, and sort out what is really occurring, as treatment of non epileptic seizures is very different. This does affect your activities, especially driving.
