If you have pain after a head impact, go to the hospital for a head CT examination to clarify whether there is intracranial bleeding. If the CT examination indicates no intracranial hemorrhage, the pain is caused by soft tissue injury of the scalp or concussion of brain cells caused by the head impact, and the pain can be treated symptomatically by giving pain relief, commonly used painkillers are Tramadol, painkillers, etc. Meanwhile, attention should be paid to quiet rest, and generally this pain can be relieved in about 1-2 weeks. If intracranial hemorrhage is detected by CT examination, the patient must be hospitalized immediately. Conservative treatment such as hemostasis is given when the amount of bleeding is small, and even craniotomy is required to remove the hematoma when the bleeding is large. If postoperative paralysis or aphasia of the limbs occurs, further treatment such as postoperative rehabilitation is required.
