The one thing about persistent migraine auras is that they are there, migraine or not. It used to be they were this awesome warning system of Impending Doom. As in I would get this atypical migraine aura pretty much an hour before the actual horrific headache portion of the show began. It was perfect for taking my migraine abortive. Talk about knowing exactly when to take your medication when you start going sparkly blind in one eye.
Not so much anymore. I have much more diversity now as well. So much more visual auras to go around. And very few of them warn me of Impending Doom. Well, not visual ones anyway. Tingling in the hands or face is pretty much a dead give away though.
But it does vary. There are the halos around a light. Where the lighter it is the harder it is to see because there is a fuzzy halo around all light sources. So if someone is standing beside a window… can’t bloody well see them. Starbursts often come with halo days… they are when you see something like headlights but the light expands outward like a star. A common aura of mine I get very frequently replaced my regular aura, but is a persistent migraine aura now, it is this broad arch of multi-colored pixels of light in both eyes over about half my vision… fluctuating and pulsing for a good five to eight hours. It expands from a small portion of my vision to a larger portion… sometimes a significant portion. Other times there are dark spots, blind spots, blotches of white, raindrops of color. Another common one that comes on in bright light exposure is a vibrant vortex of light with a blind spot in the center. It reminds me of a flower, with pedals of black, iridescent blue and pink expanding open and closed. It tends to get larger as time passes and is always in the core of my vision.
It would be like if people could see a rainbow… the colors are similarly vibrant and translucent… but fluctuating and pulsing. Overlapping reality. Distorting reality. Another aura I can get is where lines, like corners, patterns, lines all warp and contort… so that makes it difficult to look at things. But you can see how many of these things are difficult to describe. I can say sort of like some fireworks. Sort of like a twisted rainbow. I often wish I could take a picture or video of them just to share the experience. Often wish I could show them to my neurologist as well so they could understand how disruptive and distorting persistent migraine auras actually are… given they light show does not shut down, just changes from day to day.
It is sort of problematic and enchanting. In some sense, I am entranced by this light show. In a way, it is often Too distracting. It takes away from reality in ways you really don’t want it to at times when you need your attention. But sometimes I will just watch the light show because it is that fascinating what my brain is producing… this illusion. Very problematic when you need to see fine detail. Drive. Pay attention. Want to see. Things of that nature. And also very unpredictable with persistent migraine auras… you really have no clue if the phenomena will last all day or a few hours. My vision, in some fashion, is compromised in some way every day at some time…. just depends on Degree.
