Migraines are vascular headaches that occur when there is uneven dilation of the blood vessels. Imagine a garden hose that is narrower in some places and widens out in others and then becomes narrower again. As the water flows through the hose it will meet resistance in the narrower places and then flow with ease in the widened place only to “hit" the narrow places again. This is exactly what occurs with migraine headaches when the blood vessels of the head, neck and shoulders dilate unevenly.
If we can help the blood vessels to dilate evenly by ensuring our body has the right balance of vitamins and minerals, we achieve vasodilation and that leads to a complete reduction in pain.
