If the patient has headache symptoms and the nature of the headache is fluctuating pain: firstly, it is necessary to consider whether the patient has elevated blood pressure, and it is recommended to measure the blood pressure if the fluctuating headache is caused by high blood pressure. Secondly, if the patient has frequent fluctuating headaches, the patient needs to undergo a head CT or head MRI to rule out intracranial space-occupying diseases and intracranial demyelinating diseases. If the patient has recently experienced fluctuating head pain, then it is considered that the patient may be caused by neurovascular headaches, which can be triggered by overwork or excessive mental stress. It can also be caused by diet, such as eating spicy and stimulating food.
