Neurosurgery is recommended after a head fall because the diseases studied in neurosurgery include head injury, and neurosurgery has rich experience in clinical manifestations and treatment after head injury. Some patients in life have headache, nausea, vomiting and other symptoms after suffering head trauma, but they feel that they are conscious, so there is not much problem inside the skull. In fact, this is a wrong view. As soon as clinical symptoms appear, it is recommended to go to the neurosurgery department of the hospital to review the head CT, because intracranial changes are sometimes very rapid.
