When you lost your memory, did any of it ever return?
You mentioned you were unconscious for two hours, were you in Status Epilepticus and seizing or was most of that time when you were asleep after the seizure ended?
Of all the seizures I had in the last 50+ years I’ve never had a headache as a result from one.
Here is some information from the Epilepsy Foundation regarding headaches

Take care,
