Last night I fainted for no reason. I hit my head onto a chair,and then onto the floor. I jerked my head backwards to hard, and now my neck is hurting. I have a huge bump across my forehead with a couple of bruises going down my face. I have slept all day long, and it still feels like I haven't slept at all. The doctors gave me some medicine that was suppose to help the pain go away, but it still hurts. I've been having headaches and they won't go away, and get worse the longer I stay awake . What could it be? How can I make the hurting on my head go away?
