Does anybody have any idea what causes headaches? I’ve looked it up on the internet and found that they can be caused by reading or sitting at the computer too long. However I stopped doing this one day and still ended up with a headache so that mustn’t be my problem. I don’t want to bother my doctor as the headaches aren’t that bad, just really annoying. However I get one almost every day without fail and it doesn’t seem to be anything I’m doing. Could there be something wrong with me? I’m starting to get a little worried. Maybe I should see the doctor.
