What Causes Eyes To Be In Constant Pain After Vomiting And When In Motion?

Hi, i ve had problems since i was a kid everytime i get the flu and when i vomit. Every time i get the flu, i usually throw up on the first or second day, then after im done throwing up, the following days i have eye problems. (Please read through carefully, i can be very confusing :P) My eyes will sometimes be very light sensitive and they hurt when im in motion, like when i get up and walk from one room to the other or when my head moves around fast. Its very hard to explain whats happening, but my eyes hurt for a couple seconds and it feels like they re going in circles in my head, but i have to close my eyes, i can t keep them open. And at the same time, my stomach hurts, which also lasts for a couple seconds, then my eyes go back to normal. The day after i throw up, my eyes are very sensitive and i get this constant pain alot more when i move and am in motion, but as the days pass, it gets less and less worse and i can slowly move around more, and the pain i have in my eyes, gradually decreases. I am usually out for a week before i am back to normal. This usually happens 2-3 times a year, but i am baffled as to why.
