stress; if I go to long without eating; odors, esp. chemicals like in a laboratory; alcohol; too much sun. My auras is lights and a stabbing pain in my right eye like some one is poking me in the eye. When I first started getting migraines they came on sudden with the worst headache I had ever had in my entire life. Then I had a headache ever day for 9 months before the docs found the right meds and right dose to get them under control. Meanwhile I thought I was going to go out of my mind.
