Yeah I know there’s a few of us on here ( Dendy is one) that have discussed this over the years. I too get that heart wrenching , panic attack aura that lasts for 25-30 minutes. Lose your vision., see kaleidoscope shapes .. all the while knowing the hell that is about to follow. I’ve had it happen while driving on sales calls and had to pull over . In my younger days it would result in nausea .”, vomiting , pounding headaches. As I have aged the headaches are more manageable and no nausea. In fact, I went 3 years without getting any in my early 50’s.. and then this past holiday season had about 5 in less than a month including one on Christmas Day. I thought I had outgrown them as generally you do into your 50’s. For me trigger’s were General Tso’s chicken , driving with sunlight thru the trees creating strobing , and the biggest culprit of all .. barometric pressure rises and falls . I gave been to neurologists for tests and so have some triptofan medication which I do take . I have gotten multiple ones in the same day hours apart .
