OK, so something happened to me this morning during my computer animation class and I'm still not sure exactly what it was. It went like this: The teacher was having us do some exercises to counter tendinitis, and at one point, he had us stand up and put our right arm out in front of us. After I did this, I suddenly couldn't control my body anymore. My arm slowly lowered on account of gravity and I couldn't raise it back up; I couldn't move anything at all. I can't even remember the next 5 seconds or so because right after that, I passed out, fell backwards over my chair and banged my head on a desk. I jolted awake quickly enough, but it took a few seconds before I even realized I was at school. I went to the school nurse, but there seemed to be nothing wrong with me; she only suggested that I could've possibly stood up too fast and lost some of my circulation, but I was standing for about 7-10 seconds before it happened. My brother said it sounded like I may have had a seizure, and the teacher did mention that I jerked a couple of times before I woke up.
