If it is due to poor sleep, insufficient rest and brain fatigue that is not relieved, the headache can appear the next day and be relieved after rest. It is also necessary to consider whether it is caused by elevated blood pressure. It is recommended to measure blood pressure, and if it is much higher than the usual blood pressure, headache symptoms will appear, and it is dominated by head swelling and pain. In addition, it is also necessary to consider whether the patient has a past history of migraine, and if there is a past history of migraine, it can be a reoccurrence of migraine. It is recommended to go to the hospital and have a CT examination of the head, because it is also necessary to exclude headache caused by intracranial hemorrhage, intracranial tumor and other problems.
