I had migraine all my life, and i honestly do not know if it is related to ANs.
I have tried everything and some medicine worked well. It was in fact the one for arrhythmia or angina that kept the migraines at bay.
But they always had the pain in the head with it after the first symptoms which were, numbness of the nose, butterflies in the stomach, cols extremities, vertigo, nausea. Then the pain on only one side of the head. it was serious enough to be confined in bed, dark room, no noises for 3 days, vomiting constantly. Then it would go away by itself as no medicine could do anything once the symptoms were strongly in place. Now than I have aged, I have the migraines still but without the pain, so it is because of this that I replied to your post.
It still last 2 or 3 days but the only proof that it is a migraine are the symptoms and a faint tightness on the top of my right brow, which I recognize well.
