From a website about headache treatment:
A proven method of treating a headache that occurs due to a shock of the brain,
by Ubiquity. To do this, you will need a seat with wooden edges. Of course, not everyone has such a site, but if you try, you can find it.

The edge of the sit should be pressed with teeth so that the face is inside its surface. Then gently hit the fingers of your left hand on the right side of the sit, and then hit the fingers of your right hand on the left side of the sit. Then with the palms of both hands also gently hit on both sides of the sit. Make sure that the powder is the same. These actions can be repeated again.
And in the evening of the same day do the following: stand face to face to a smooth surface (painted, polished, canvas, mirror - any), lean your forehead and nose (remember how in childhood you pressed to the window window) and start to sit slowly, without opening your forehead. The forehead will begin to jump down small steps, there will be vibration. This is the method of treatment. The pain goes away very quickly, sometimes even after 3 sessions.
Whoever does not believe, let it be checked!
