Given the critiques from medical professionals here, I’m not qualified to speak to the accuracy of this article. But it makes me think of a partial cure for migraine pain I discovered by accident over 45 years ago. I’ve suffered severe migraine headaches since childhood and one time during the aura I made myself cry and never got the headache. Thereafter, during the aura phase I found that if I could cry, about anything, I wouldn’t get a headache. I might get the severe fatigue and some nausea but they were preferable to the terrible pain in my head. Well after menopause the headaches became optic or ocular so that I rarely got headaches even without crying. Perhaps I unwittingly induced a vagal response and reduced stress through crying that prevented the headache stage of the migraine? I recommended it to others and they had some success.
