We Are on vacation and My 13 yr old child rolled over In bed and .... Because these double beds are small he rolled over and hit his chin on the corner of the night stand that has a sharp edge. He did gash open his chin.... Luckily I carry butterfly badges and new skin so I was able to stop the bleeding. He is resting in bed with some ice on it. My question is can he have a concussion from this? Right after it happened he said he felt lightheaded and like he was going to throw up. I applied a cold wash cloth and then when my husband got back with the ice we applied that. I ve been waking him periodically.
