If a child falls out of bed and has a headache, the first thing to do is to clarify the child’s condition, observe whether the child’s mental state is good, whether there are symptoms such as vomiting and fever, and then observe whether there is any redness, swelling, heat or pain at the site of the fall. If the child is in good spirits and does not have symptoms such as vomiting or headache, it is advisable to observe the child first. If the child is not in good condition, with symptoms such as vomiting and depression, it is recommended to go to the nearest hospital for a head CT to diagnose whether there is a concussion and traumatic hematoma bleeding, and then treat the symptoms.
