I used to suffer from these auras from 2005 to 2015. I never had one before, and they completely disappeared since then. I don't think they were ever followed by any headache, either. A funny but related story: I was visiting Paray-le-Monial where there's a diorama about the visions of Saint Margaret-Mary ( https://en.wikipedia.org/wiki/Margaret_Mary_Alacoque https://en.wikipedia.org/wiki/Margaret_Mary_Alacoque ), who is at the origin of the current cult of the "Sacred heart of Jesus". In fact from the descriptions, it's very clear that the brilliant, shimmering lights that she related as her visions and revelations of the "Sacred Heart" were simply scintillating scotoma from her migraine, then followed with terrible access of headaches that she interpreted as her mystical ordeal from God.
