Reply to comment by Ardet_Nec_Consumitur in Researchers have found the genetic links between headaches, migraines and blood sugar levels, which ultimately could lead to targeted treatments for patients by giuliomagnifico

Caffeine actually makes your blood vessels constrict, not relax. From what I know, migraines are an abnormal response to the blood vessels in your head relaxing, and normal headaches can be caused by dehydration too. Caffeine helps because it raises your blood pressure by making your blood vessels constrict. That's why some headache medications have caffeine in them. Drinking enough water also helps because it raises your blood pressure. I noticed my migraines became less frequent when I started drinking coffee regularly and making sure I drink enough water, along with avoiding other triggers.

If your migraines are neck pain related, then the relaxation/masaage can help too.

caffeine is a vasodilator. However, dependency (or going cold turkey) on it causes the vasoconstriction

It acts as a vasoconstrictor to the blood vessels in the head, it produces cerebral vasoconstriction by antagonizing adenosine receptors

Ok I'll take your word for it. But do you have any idea why drinking coffee or taking caffeine tablets completely removes my migraine? I mean in the moment when I experience the onset of a migraine, I just consume caffeine and it disappears!

Probably because your migraines are due to vasodilation, caffeine will antagonize that and restore a pain free vascular state. For what it's worth, I experience if not the same a similar situation as yours
