An Underlying Disorder
What else can I say but… there are those who are innately intuitive.
Considering the cause of headache and migraine, I have just come across a gentleman(1) who in 1888 described the migraine process in this way: “… we must not ascribe too much significance to throbbing of the increase in the pain by the cause of vascular distension; these may be due merely to the over sensitiveness of the central structures.”
A man almost 130 years before his time – Bravo!
In other words expansion of the blood vessels is unlikely to be the cause of pain; it may be that (normal / subclinical) expansion of blood vessels is misinterpreted/magnified by a sensitised central nervous system.
This information from the blood vessels has to pass through the BRAINSTEM on the way to the cortex … and what has been shown to be the disorder in headache and migraine? A SENSITISED BRAINSTEM.
