The : The scalp (the skin on the head) is well-supplied with blood. Even a small impact can break blood vessels, which can cause a big bump. So, a lump on the scalp isn't a good measure of how serious an impact is. The more important consequence of a head impact is concussion, a brain injury. Signs of a moderate to severe concussion include getting "dinged" (briefly stunned), or any loss of consciousness. In general, experts recommend that a child be seen within 2 days of any significant head injury, and should be seen right away if they show any signs such as memory loss, headache that doesn't get better or gets worse, mood changes, balance problems, or vomiting. It is very important to avoid a second head impact. Children should wear helmets when riding a bike or engaging in other activities that may involve a risk of head injury (including skateboarding, rollerskating, skiing). A helmet that was involved in an impact should be destroyed and replaced.
