I suffer from medium facial pain for three years already. It comes up one or two times a month (sometimes even more often) under my left eye or left cheekbone. I went to neurologist but after MRI test he said there is nothing. Then I went to dentist, who found infection in one of the last teeth and fixed it. But the pain still came up. So after that I visited another dentist who said everything with my teeth is OK. Sometimes I even have to take painkillers to stop the pain. I have no clue what kind of doctor should I visit next?
