I have similar auras but gave up talking about it as no one seems to understand. I was just told I am celiac about 4 years ago and then it was confirmed about two. Sometimes I have gluten ataxia which was previously thought to be ms! I often see floating purple light, have very blurry vision and sometimes a migraine comes but not always. I have about 30 food allergies and citrus is a big trigger of migraine for me. I have been told that my food allergies are due to my celiac but in celiac support group no one else mentions this problem. One of my doctors told me that I have seizures due to odors and sprays which I do believe may happen. They are not typical tho.
Thanks to all of you who posted thereby helping me to understand this better.
