Hello, I am a neurologist and i thank you for posting this question in HCM First of all i would like to tell you that headache can be due to various reasons (like brain tumor, infection, vascular malformation of brain, migraines, idiopopathic intracranial hypertension etc) and the main aim of the treating doctor is to identify the cause of headache and deal accordingly rather than simply assuming the diagnosis. Back to your question, as you have seen a neurologist and he has opined it as migraine after MRI scan, i agree with the diagnosis. You have the following options 1. management of migraine: Note that migrain is a disorder of brain and it improves with age. There are two treatment aspects. One is to deal the acute severe attack where in you can use analgesics, sumatriptan nasal spray. Learn relaxation and avoid the precipitating factor for migraine like coffee, lack of sleep, stress, perfumes etc. You have other options for migrain too like sodium valproate (note that this medicine can cause weight gain, menstrual problem if you are a female), topiramate, amitriptiline, propranolol etc. Either you can increase the dose of the current medicine to 50mg or even 75 mg and watch for the response or opt for another drug 2. As migraine is a diagnosis of exclusion, you get re-examined by another neurologist and secure the diagnosis and deal accordingly. You may check your eye pressure too Hope this will help you Regards
