If you have had headaches before or if your parents or children have a history of headaches, you may be suffering from migraines. Migraine is a disease, and not all headaches on one side are called migraine. Migraine has a family history of inherited disease, and attacks take the form of throbbing-like throbbing pain, with an attack lasting 4-72 hours, accompanied by nausea, vomiting, photophobia and phonophobia in severe cases. Fatigue, drinking alcohol, strong tea, coffee, eating soy sauce and MSG are all triggers and are treated with oral naproxen and flunarizine as necessary. If there is no previous history of headache, it may be neurological headache, sometimes related to cold, or it may be caused by high blood pressure, which requires diligent blood pressure measurement, and it may also be cerebrovascular disease, so if necessary, go to neurology to do cranial CTA or MRI to exclude cerebrovascular disease. If there is blood vessel stenosis or intracranial aneurysm, prevention must be done.
