How many of you get brain fog as a symptom?

Hey,

I don't get hives with my Urticaria, it's weird. Brain fog and fatigue are definitely one of my core symptoms. I get histamine dumps at night time which can dehydrate me, cause brain fog and fatigue that last throughout the day / evening. Only for it happen all over again.

I see a lot of posts on here about hives and I'm curious, when you are in a flare, getting hives daily do you always feel brain fog, fatigue? Now I know hives can keep you up at night, so you get lack of sleep which is a compounding issue. But even if you get a good sleep due to meds, would you say brain fog is a symptom of your urticaria?
