Yesterday, just as I was stepping into the shower, I saw a migraine aura. People who deal with migraine aura experience visual, sensory or motor disturbances just before a migraine attack. This phenomenon usually lasts an hour or less, and symptoms may range from seeing sparks and zigzags to the inability to speak clearly. For me, it is mostly the sparks that I see, and it usually lasts just a few minutes. I don’t always see an aura before a migraine, but a migraine always begins sometime in the next twenty-four hours after the aura appears.
When I was younger, the migraine began almost exactly
When I was younger, the migraine began almost exactly twenty-four hours after I saw an aura. In the last few years, I normally have about thirty minutes to an hour before the migraine sets in. Yesterday’s was a slow progression. It started out mild, so I went to work and tried to work most of the day with my office lights off, but by mid afternoon, that wasn’t working for me anymore. The pain was intensifying and continued to get worse over the course of the evening. Eventually, I just went to bed.

Know this well. I see the shimmering line and/or strobe light about thirty minutes before it begins. Twice, the migraine began with my field of vision shrinking until I was completely blind and had to feel my way to the bathroom to vomit. The last time that happened was 18 yrs. ago. I could not think things through for almost two days afterward. I struggled to figure out how to drive to the grocery store. It took two hours to make my purchases and check out whereas it usually took me 30 to 45 minutes. I have had times when I knew the migraine was coming as triggered it intentionally to get it over with. My migraines are far fewer and less intense than yours and I doubt that you could or should do that, I was able to go back to work after the triggering the migraine for the weekend. I can relate to what you describe.
