hi, I too have a headache if I shake vigorously but not always;I noticed a few years ago and since then use this as a test to understandthe health of my head ......., that is if it does not hurt to say that everything is fine,if after the shaking is very painful to say that already I have a headache or that it takes very little to get him, so in this case I try to shelter the head / neck from the cold,
if sudo in the back of his head / neck try to dry off with the phone, I'm careful to eat light because I noticed that our headaches can sometimes be triggered by digestion.our headaches can strike: the head and neck, the band above and behind the ears, even the top, sometimes from the top, down the neck and front of and behind an ear as if it were due to inflammation of a nerve ...other times it seems to be inflamed both the brain (meningitis, encephalitis)I think we have an inflammation of viral origin probably at the origin of the ME.
forgive me .... I translate with google ...good night
