Getting rid of headaches fast is a matter of knowing what causes your headaches. For me, for example, one surefire way to get rid of a headache fast is to take a couple of Excedrin and go lie down. Usually, mine are caused by bright lights and sound, so lying down in a dark room with everything off helps. However, drinking water or eating some food could be all you need before you should pop the pills.
Sometimes a vitamin or mineral deficiency could be making your headaches worse or less likely to go away. In this case, the only quick fix is to go see your doctor. Honestly, if the headache lasts more than a couple of days and you’ve tried everything you know of, it’s best to go see a doctor. Headaches can be serious signs of other problems, so they aren’t to be taken lightly.
