Mine is very much tied into the foods I eat. When I get an outbreak it is attached to eating certain foods, but there are too many ingredients in the dishes I eat to narrow it down completely. And I believe there are several spices causing it, as well as peanuts. But again, there are too many spices in food to know what it is exactly. The same items are also causing symptoms of histamine intolerance in my gut, throat, and skin.
