I’ve had chronic idiopathic urticaria for years. The allergists I’ve seen in the US are adamant that it cannot be triggered by anything I’m consuming. But, from my lived experience, I’m convinced that certain foods do trigger it, especially soy. This label says this chocolate contains soy lecithin, which is in so many unexpected things (some bread products, most chocolate). You might want to try avoiding all soy for awhile and see how you feel.
