It is recommended that babies who have fallen and injured the back of the head go to the hospital to be examined by a professional physician, and if necessary, combined with the results of imaging tests to determine whether there is something wrong, so as to avoid making their own judgment and missing the opportunity for treatment. Due to the fragility of the skull and poor speech ability of infants and young children, even if there is craniocerebral injury after a fall, it may not be obvious. It is not recommended to judge on your own after a bone injury. It is recommended to go to the hospital for a neurological examination and a cranial examination to find out whether there is an abnormal hematoma in the scalp, an abnormal shape of the skull, a skull fracture, an abnormality in muscle strength and tone, or a neurological impairment. For those with symptoms of skull fracture or neurological injury, and may have abnormal crying and obvious lethargy, it is recommended that further imaging tests be performed to determine whether there is intracranial hemorrhage or brain damage and the extent of the damage. After a fall, it is recommended to go to the hospital in a timely manner to avoid delaying the best time for treatment, and need to follow the doctor’s instructions for reasonable treatment.
