I was in a car accident a few days ago. My head hit the window and I lost vision for a moment. When my vision came back, it remained blurry. I know I felt weak for the rest of that night. My head is extremely sensitive now. The slightest pressure, even from my pillow causes pain that I would compare to a migraine. The light and all noises cause discomfort and make me feel nauseous. I also feel fatigued. This isn't like me, I'm usually full of energy.
