Hi.. welcome to HCM.. thanks for the query.. you have been treated for migraine. unfortunately migraine has no complete cure.. it can have recurrent attacks even after using medicines.. the best you can do is to reduce attacks by avoiding triggering factors like strain physically and mentally, lack of sleep lack of food, and taking certain food like dairy products or chocolates etc., treatment can be prolonged if the symptoms are severe.. you can go for botox injection also for severe headache but it gives only temporary relief.. so try to avoid the triggering factors which lead to headache.. you can continue NAXDOM if you have pain. hope this information helps you .. take care..
