So just smacked my head in the back of my head. Was tying my shoe and smacked my head on the hand towel holder mental on. Hurt a lot at first like grip my head and was like holy shit this hurt. But that was at 144 it almost been an hour and don't feel nauseous and no headache minus wereni hit it. And don't feel dizzy. Tired but didn't sleep well last night. But scared please any answers would be amazing.
