Did I have a seizure or something else?

Yes you did. I get seizures and when i seized my body starts vibrating, eyes go back, ure tongue feels like if you are going to swallow it, some people pee or poop then you black out. When you wake up you are dizzy, tired and your whole body aches. Also I will have bites on my tongue. I have gotten tested for everything and they still cant find anything. I am 20 and I have been with this condition since i was 13
