I always get a banging headache before I have a seizure. Its one of my warning signs.

I get headaches after a seizure almost every time.

There is no such thing as a silly question. It is possible to have headaches after having a seizure. It depends on the type of seizures you have and, in some cases, was from TBI?

I can get a 24 hour chronic migraine afterward.

The main answer to that is Yes. It just like some of us end up angry , depressed , laughing , crying and a few other after effects, when coming out of the seizure.
