I have been having a sharp pain on the left side of my face, it can go from my teeth to my eye. I have been to the dentist, he said there is nothing wrong with my teeth. It is not a constant pain. It usually only lasts for a few seconds. There is no rhyme or reason when it happens. It has happened when I am sleeping, once when I washed my hair, I hit a certain spot and it triggered the pain, sometimes when I brush my teeth, or apply foundation to my face--but not every time. Im not sure what type of Doctor to even see. Can you help?
