Injuries to the head from being hit by a brick will vary depending on the size of the force and the location of the injury. Where the force is not large and the bone is thick, there may be scalp swelling, scalp hematoma, dizziness and other symptoms, most of which do not require special treatment. If there is scalp swelling and scalp hematoma, local cold compresses and hot compresses can be applied, and attention should be paid to rest, and most patients can recover on their own. If the force is relatively large, or the bone is relatively weak, easy to skull fracture, intracranial hematoma and cerebral contusion, most of the patients have a headache, nausea, vomiting and other symptoms of increased intracranial pressure, we should go to the hospital in time to the hospital, craniocerebral CT examination, based on the results of the CT examination, to take surgery or conservative treatment.
