hi, lately ive been suffering from severe headaches which im told are migraines because I get nausea and feel like vomiting, the light bothers me and I can barely stay on foot, without feeling like im going to fall over. it feels horrible and one of my friends was reading about it and told me that my birth control could be causing this, the dr gave me anti depressants but it seems like they are not working because im getting the migraines more often and they last more than a day, the last one lasting four days in a row. I need help, what should I do? thanks for your help.
