Well, I came back from school, went downstairs to play on my computer when my vision started to blur. I couldn't focus on anything. I went upstairs and on my way up the stairs, the top of my eyes killed and the back of my head throbbed. I lied down on the couch only to find it increase the headache. I couldn't go to sleep because my eyes became extra-sensitive to the light and it killed. I went into my room, blocked all sunlight and finally slept. Neither Tylenol nor a allergy medication helped. Anyone know how this is caused? And yes, I'm fine now but having random headaches every 30 min and I can't run up the stairs.
