So today at school, my teacher started talking and she was behind the desks, so I quickly turned around. Right then, I hit my funny bone on the curve of the chair (our desks have chairs attached to them). After that, I couldn’t feel my middle finger or a little bit of my ring finger. I understand that part, but I don’t understand this: A few seconds later, blue-ish green spots appeared in my vision (kind of like when you look at the sun and that spot is there), and I started to feel like I was gonna throw up. About a minute later, I was perfectly fine. Anybody have an answer or hypothesis for this? It would be greatly appreciated
