Head injuries are common in active kids and there are three main types: scalp injury, skull fracture and concussion. In this episode, Dr. Gellner tells you what the most dangerous head injury is and what to do at home if it happens to your child. She also talks about signs to look out for after a head injury that would require a follow-up with your pediatrician.
