I swear year by year my visual migraine aura gets worse and worse. I hate light of all sorts and maybe that is because I get the light senetivity from FMS as well as migraines, either way light is painful and a migraine trigger. The lighter it is the more intense my usual prolonged aura of visual snow is... all those billions of sparkles creating a wierd warping current in the air. Then before a migraine the visual snow gets brighter and the specks larger, as well, I get a sort of murky ink that flows through my visual field. Sometimes I also get the warping, flashing negative aura. Recently I noticed in the morning when I first exit my completely dark bedroom and go into the hateful light that I suddenly get an intense flashing aura that completely obscures my vision for five to twenty minutes. Very Intense.
