hi i have had a headache all day and now it feels like my left eye is bruised although it is not. i have frequent headaches sometimes my vision blurs a little however my eyesight is fine. one day a couple of months ago i had the worse headache ever, i didnt want to talk or watch tv; bright lights and loud noises made me feel worse so i went to bed in the dark. my headache was so bad that i couldnt sleep i got maybe an hour sleep then id wake up because the pain was so sore. id be up for at least three hours then get an hour sleep if i was lucky. this happened throughout the entire night and my headache still lasted the next day and my left eyelid was droppy. a year ago i was in a car crash, we crashed into a bank/hill however i never went to a doctor to get checked, maybe this is the cause for my headaches?
