Ive Been Having Headachds Off And On For The Last

Ive been having headachds off and on for the last 6 years ill get 4 a week for a month or so then itll go away for 8 months and then contuine with headaches for about a month only on one side of my head behind my eye. After it being gone for almost a year ive had 5 or 6 headaches a day for the last 2 weeks feels like im having a stick going through my eye and my head feels numb and a burning hot sesation. It hurts so bad that it makes me sick.. what do you think this might be? Or what should i do? Every ER doctor or even my own doctor says its nothing just a common headache
