Is it possible that cholinergic urticaria depends on your body adapting to heat/sweating?
Like in my case, every winter when my body temperature rises, I get CU. In previous years it would go away around March–April.
But I think one difference was that I still used to go out, cycle in the sun, and sweat a lot (even though it triggered it).
This year I completely avoided heat and sweating, and my CU didn’t go away even till end of April. Then when I started sweating again, it improved and went away.
But when I stopped again, and after one rainy day (temperature drop), it came back the next day.
Now it’s literally 48°C and I still have CU.
I used to think that in future I’ll just go to a hotter country to get rid of it, but I don’t think it will change anything my city temperature literally peaked at 50°, people are literally dying in my country because of heatwave😭
So I’m wondering does the body actually need consistent exposure to heat/sweating to “adapt”, and if you avoid it, it just stays sensitive?
Has anyone experienced this pattern?
