Chronic Urticaria

Pro tip: Use google.com

Yes! I have suffered with it for many years. Splotchy full-body rash that comes on without notice, stays a few days and then disappears. Sometimes related to stress, illness or over-exertion, but not always. Doesn't itch, is not particularly painful -- just unpleasant and unsightly. Have seen many doctors about it on three continents, but there is no known "cure". Can be mitigated by taking antihistamines, particularly Zyrtec. Used to go to England to get supplies of that, but thankfully it is now available OTC here. Whenever I feel a rash coming on, I dose myself with Zyrtec and it seems to help. Rash usually appears first in groin area, then on legs and arms. Sometimes accompanied by general achy feeling, but otherwise can almost be ignored and it will go away.
