Headache might be migraine. Doctors?

Hi, From past couple of years I am suffering from headache. I consulted many doctors including my family doctor who is psychiatrist. After consulting them I used to get relief for couple of weeks or months. But again it used to occur. So I used to consume NT GRAIN and PARANIM tablets which was suggested by the normal medical store guy. I started using it but I addicted to it too.. I used to consume once alternative days or twice a week.So again I consulted doctors regarding the headache issue. But I didn't reveal that I am consuming those medications. Some doctors said that I have sinus issue hence I underwent sinustinus surgery 2 years back,since I had deviated nose bone too. This surgery released me from my nose issues and to some extend my headache too. But again I started getting headache and if I consume NT Grain and Paranim tablet I will get relief from it for 2-3 days. But my aim to get rid of those medication consumption. Hence please help to to get out of this addiction.
