Temporal pain on one or both sides is pulsating, slowly aggravated, and can be repeated, often accompanied by nausea, vomiting, photophobia and vomiting, sweating, and general discomfort. The frequency of attacks is high and the headache lasts for a long time, up to several days, and the pain is often accompanied by contraction of neck muscles. 2. Migraine with aura, also called typical migraine, mostly has family history. Clinical symptoms are typically divided into three phases: ① aura phase: the most common are visual aura such as flash, dark spot, bright line, blurred vision or distortion of vision; followed by sensory aura, sensory symptoms such as numbness, abnormal sensation; speech and motor aura are rare, and aura symptoms usually develop gradually within 5-20 minutes and last no more than 60 minutes. (ii) Headache phase: the pulsating pain on one or both sides of the frontotemporal or retro-orbital area appears simultaneously with or after the aura symptoms, often accompanied by nausea, vomiting, photophobia and vocal aversion, pallor or sweating, etc. The headache is aggravated by activities and can be relieved after sleep, generally peaking in 1-2 hours and lasting 4-6 hours or more than 10 hours, and the frequency of attacks varies. ③Late attack: after the headache disappears, there are often fatigue, tiredness, irritability, weakness and poor appetite, etc. 3.Chronic migraine refers to the change of migraine attack characteristics in the course of months to years without excessive medication, and the number of migraine attacks reaches or exceeds 15 days per month for at least 3 months, and the headache has migraine characteristics.
