Passive heating and active heating history

Hey everyone,

So I’ve been dealing with cholinergic urticaria for the past 5 months. My hives were worst when I was on an elimination diet consisting only of fish, brown rice, and lettuce.

When I started eating fats and a varied healthy diet again, interestingly, my passive heating symptoms went away, and now I can take hot showers and lay in the sun without getting hives. But if I hike up a mountain, I will get hives.

I know now that hives play a crucial role with my cholinergic urticaria. I think my CU might have developed after I was on a low/no fat diet for months, before the elimination diet.

So now I just need to figure out how to stop the active heating hives too. Has anyone had an experience with CU like this? Interesting– such a mystery these bodies are.

Thanks,

-Mikayla
