I started having absent/occular migraines when I was going through menopause. That was 28 years ago. I was working long hours on the computer doing Excel spreadsheets. That instance began with a backwards C in each eye. I was afraid I was having a stroke, but otherwise felt fine and needed to finish my work project. It lasted about a twenty minutes to a half hour. Eventually I was checked out by a neurologist who diagnosed me with absent/occular migraines. Over the years, Ive had times where I’d have them every other week or so but typically in just one eye. Other times I will go for years without having any. Rarely I do get a minor headache that doesn’t usually require taking any medicine to relieve it. Mine usually start in the center of one of my eyes and slowly move to the outer aspect of that eye until it fades from view. Visible when my eyes are closed. People have posted online of what their aura looks like and it’s interesting to see. Mine typically have moving light blue, black, white and yellow zigzagging moving lines. But not always those 4 colors together. I’ve found mine to be typically triggered by exposure to different types of bright light or being stressed. Now I track them on my calendar and just sit back, close my eyes and enjoy the light show!
