My husband is having frequent headache... he's under ayurvedic medication. Migarot and perment tablets almost from a month.. he doesn't have any other symptoms like vomiting or nausea or vision problem.. doctor says it's migrane.. but I'm worried cox even after taking medicine for so long , he's getting headache very often like alternative days or 3 days once .. but headache is mild and intensity has reduced he says.. But y is he still getting headache often and will not completely reduce after medication?? shld we get a scan done ??
