Good question: Hives (or urticaria) represent a sensitivity to something dilating the small vessels under the skin, causing a raised pink lesion; if u press on it, it will blanch, let it go it pinks up again. Many causes: foods, chemicals, perfumes, very often stress. Stress can increase acid formation in stomach, Zantac (ranitidine) reduces it. Over 50% of time, one can't find cause. I treat initially c antihistamines.
