I'm really not sure if what I experienced was a seizure, and hopefully someone here can help me out.
I was cleaning up a mess my dog had made on the floor, and I stood up to put the soiled paper towels in the garbage can. When I reached the can, I got very light headed, sort of the way you feel when you stand up too quickly. I reached out and steadied myself against the wall, but rather than fading like it normally does I started shaking. I wasn't twitching, but my whole body was shaking back and forth and everything went dim. I couldn't control it at all! I had to struggle to keep my legs under me. After it passed, I felt really run down like I was sick, and I had to lie down for an hour.
I work with children with autism, so I've seen all sorts of different kinds of seizures, but I've never experienced one first hand. Does this sound like a seizure to anyone?
