Hello, i am a neurologist and thanks for posting this question in this web site The causes of headache are so many and the approach to any patient with headache begins with a search for the exact cause of headache. The common causes of heacahe are migrain, tension headahce, brain infection, tumor or problems in the blood vessels of the brain and so on. Back to your question, you have assumed that you have migrain headache. How ever, one has to understand that migrain is a diagnosis of exclusion (the above cause need exlusion before we say that headache is due to migrain). If a CT scan rules out these possibility, the diagnosis of migrain will be confirmed. Coming to tghe management of migrain, there are two aspects 1. To treat the acute and severe episodes- this can betreated with analgesecis. other medicines which can be used are triptans like sumatriptan nasal spray can be used provided that you donot have any cardiac problem.2. To treat t the chronic phase or the medicines that can modify the headache-for this the options are sodium valproate, (this drug has a good evidence for this headache, but in females it may cause weight gain, menstrual irregularities), topiramate (it cause weight loos too, may be a good options if you are obese), amitryptiline, propranolol etc. Apart from this one has to find out what triggers the headache like stress, food, perfumes , chocollate, coffee. These life style modificationa also help decrease the headache. Hope this clarifies Best wishes
