You will be surprised, but the headache is not related to vascular spasm or osteochondrosis, how many are used to asserting! Does everyone's head hurt...... is it normal?... because of a change in weather?... because of high blood pressure?... need to undergo an MRI?... because of a brain tumor?... after a concussion?... because of the cold? Even though the headache problem is extremely common, until now, the wildest false beliefs about what is its cause and what treatment approaches are effective. This book will contribute modestly to debunking such myths. Myths, many of which can be dangerous to health. And life!
