Only one side of my head hurts. It will start to hurt if I am exposed to broad daylight or anything that is too bright. I experienced also ringing on my ears. I dont know if its related to my poor eyesight but sometimes before I have this throbbing pain in my right or most of the time my left head including my right eye, I am having visions like colors lines or worst everything is blurred. I also experience feeling nauseous and vomit all the time my head hurts.
