Hi.. You may be having one of the chronic headache syndromes.. Some thing similar to migraine.. Usually these headaches are triggered by a factor which you need to check out and avoid them.. Be regular with your sleeping habits and regular diet is a must.. And when ever you feel that you may have an headache, take your pain killer as early as possible for better effect.. Get your eye checked to see if you have any vision problem and if glasses can help you.. Consider consulting a doctor when you feel the headaches is going out of proportions and there is not relief with the medications..
