I want to treat cholinergic urticaria ㅠ

I need a place to vent because treating cholinergic urticaria is really difficult and frustrating.
I have written this.

I have a condition called cholinergic urticaria.
As a result, daily life has become extremely difficult.
Is there anyone experiencing the same symptoms as me?

At first, I thought it was just a simple skin rash and didn't take it seriously, but
The symptoms seem to worsen as time passes.

Just exercising or going outside on a hot day
I have a rash all over my body that is itchy and stinging.

Every time that happens, I really go crazy. I take my medication,
Applying a corticosteroid antihistamine cream only provides temporary relief and does not completely cure it.

I have visited the hospital several times, and all the doctors as well.
You have suggested various methods, but
We have not yet found a definitive treatment for cholinergic urticaria.

Someone suggested changing my eating habits, so I tried adjusting my diet as well.
I also tried meditation and yoga to reduce stress.
Still, I haven't seen much of an effect, so I'm feeling very exhausted.

If there is anyone who has overcome cholinergic urticaria treatment,
Could you share which method was effective?
