The skull itself is very hard, so normal external forces rarely cause skull damage. If the external force is too violent, the fragile blood vessels in the neck, back, and head will become "victims."
First aid: If you have a bag on your head, applying ice packs to the affected area can reduce edema. If the head begins to bleed after being injured, the treatment is the same as that of the cut, that is, press the wound with a clean towel to stop the bleeding, then go to the hospital to sew the wound and check for internal injuries. If the injured person faints, then an ambulance needs to be called to the hospital quickly without delay.
Absolutely: Do not let the injured fall asleep alone. Within 24 hours of being injured, someone must accompany the injured person. If the injured person falls asleep, wake the injured person every three hours and let the injured person answer a few simple questions to ensure that the injured person does not have Coma, no intracranial injuries, such as concussion.
Bright alarm: When the injured person has convulsions, dizziness, vomiting, nausea, or obvious abnormal behavior, he needs to be hospitalized immediately.
