Whats happening is when you get a migraine, the blood vessels in your head are dialated, therefore the body uses blood from extremities and smaller organs(ex. skin) to fill and flow through the dialated veins.
THis is why so many people suggest Biofeedback, because you learn to increase the temp. in your finger, meaning you are restoring the blood flow, diverting it from the dialated blood vessels
