What you actually need is to stay on an antihistamine long-term—daily, month after month...
plus follow a diet free from preservatives and avoid any heavy physical exertion for at least two hours after eating.
Unfortunately, this sounds like a chronic situation.
AVOID these:
1. Canned goods, jarred items, anything in a tin.
2. Tetra Paks, unless it's just plain pasteurized milk (and definitely not chocolate milk or anything flavored like that).
3. Processed deli meats from the grocery store—you can eat meat if you make it yourself, provided there aren't extra preservatives besides salt.
4. Obvious preservatives, like various acids, pepper, Lawry's, or other spice blends—they are all loaded with additives.
5. Store-bought sodas (fizzy or still), fruit juices, or teas (including those tea bags; basically, any colored drink). WATER IS YOUR BEST FRIEND!
6. It would be best to bake your own bread, because commercial bakeries are always pumping in additives and preservatives.
I'm with them on that.

In cases of physical urticaria—specifically Cholinergic Urticaria—one might try increasing the antihistamine dosage beyond the standard amount, provided you coordinate that with a dermatologist.
Cetirizine (for example, Zyrtec or Cetirizine Sandoz) has worked well for many when taken at a double dose, essentially 2x10 mg daily.
If that still fails to provide relief, an older generation antihistamine might be an option.
Your first step should be consulting a dermatologist, if you haven't already, to secure an accurate diagnosis and discuss the possibility of exceeding standard dosages.
On the bright side, if this is indeed Cholinergic Urticaria, it often resolves on its own after a period of time—usually after several years, averaging about seven.
THANKS, I know a bit more now. 🙂
