Yes Tip.. that was a fantastic description of exactly how my migraines unfold. That visual aura where it’s initialy a blind spot where you lose vision. That’s when you know what is about to happen and are overwhelmed with dread and fear for what’s about yo transpire. You can be having a great day and the second that hits, a dark cloud consumes you. Then the wavy lines and weird shapes and colors like looking thru a kaleidoscope. That lasts 20-30 minutes for me. Smells, sounds, any human contact is not wanted. Darkness is the only help until vision returns. Then the massive , pounding headache begins. Starts as a low throb and escalated quickly to hammer pounded over head. I used to throw up and get nauseous in younger days. Can recall pulling over on roads and highways after having to leave work and vomiting. I used to get 20-30 a year. When I hit my mid 30’s.. they stopped for several years. They then started up again late 30’s and continue now. I had one just last week . But they now generally do not cause nausea. I have a Triptan pill I take at aura onset and it helps minimize the effects to some degree. I have found my triggers are mainly due to light. Flashing lights, sunlight while driving thru the trees are huge. The other one is when strong high pressure is building in. Always on a bright, dry clear day when HP is pressing in. And usually in the mid morning. The one last week was no exception. Barometric triggers for me are huge. All related to the brain. They are completely dehabilitating and force you to alter your work , your life, and for me.. it’s a constant “in the back of my mind “ fear.
