I've had all the diagnostic testing in my brain, there's nothing pressing against the brain. It's all normal, also get lightheaded, and it all starts before the pain comes.
its a lot of things. meds, aura seizure, and/or a non epilepsy seizure. it probably the meds side effects.
Those are all symptoms of when you wake up from a seizure it's all got to do with how hard your brain is working and how much electricity is going through the brain while being unconscious your brain is working much harder when you go into a seizure
