Triple Burger Triggers Migraine - Culver's, Bloomington Minnesota

Bloomington, Minnesota, United States

I had a triple burger with cheese without the bun there. The next morning I had a terrible migraine headache. I typically cook my meals at home and I haven't had a migraine like that in 10 years. I'm very sensitive to nitrites and chemicals in food, but as far as I can tell their burgers don't have any added nitrites. I can't be a hundred percent certain that this food caused the migraine but it seems suspicious. | Symptoms: Headache, Migraine
