At least 90% of migraines are caused by:
• Contractions in the shoulder and neck muscles (temporary disorder).
• Overeating (temporary disorder).
• Faulty position of the spinal cord (chronic disorder).
For the first two causes, all one needs to do is lie down, move the neck and shoulder in slow motion, and then fall asleep.
Chronic disorders instead are generally due to poor postures that one assumes during the day and from the resulting deformation of the structure of the spinal cord. In some cases, these imbalances are also due to tight shoes or to dental work that has deformed the natural position of the jaw. Once the posture error is specifically identified, the pain disappears immediately.
But in order to obtain such results, you need to consult a specialist and take a brief course. There are various re-educational "schools": Meziere, Alexander, isometric exercises, and other similar courses.You will find dozens of recommendations in New Age magazines. Take time to choose the one that is right for you.
N.B. In some cases, headache also has concomitant causes of a purely psychological nature. The general discussion on passive meditation, relaxation, changing your point of view on life, etc., is therefore valid.
