Usually my headaches develop ofter the course of the day and the following works for me (I did have migraines as a kid alot, but I’d rather not discuss the medicine I used for that if you know what I mean):
> I swear by this trick, but it doesn’t seem to work for anyone else. Try to blow wind up your nose. Just place your lower lip over your upper lip and blow away. It doesn’t cure, but it always makes me feel better for at least a couple of minutes.
> Most of the times when I have a headache it’s from my neck turning into a big knot, massaging it or taking a warm bath does help. It’s hard to massage your own neck, so I take a long towel and I rub it over my neck (like drying your back after a shower, by pulling at the ends of the towel), which seems to massage it and warm up the muscles in my neck (helping them relax).
