17 & 18
17. This may sound bizarre, but find a very aromatic mentholated muscle rub (BenGay® with the scent works great) and carefully apply a tiny amount to the part of your head that hurts. This works best on headaches that attack your face, such as under the eyes. Be very careful not to get this stuff in your eyes (you have enough trouble without having your eyes burn). The aroma of the cream will cause your eyes to water and shut. Be sure you can lay down for a while and rest.
18. This is an old wives’ tale but it has worked for some old wives. If you feel a pressure headache coming on (where the inside of your head feels bigger than the outside of your head), peel some onions. This will cause your eyes to water and your nose to run—and it relieves the pressure.
