Hives, a common allergic reaction that looks like welts, are often itchy, stinging, or burning. They may appear anywhere and last minutes or days. Severe hives can cause difficult breathing (get immediate medical attention if this occurs). Medications, foods, or food additives, temperature extremes, and infections like strep throat can cause hives. Removing the trigger often resolves the hives in days or weeks. Antihistamines can provide relief.
Urticaria (from the Latin urtica, nettle (whence It. ortica, Sp. ortiga, Pg. urtiga, Fr. ortie) urere, to burn) (or hives) is a kind of skin rash notable for dark red, raised, itchy bumps. Hives is frequently caused by allergic reactions; however, there are many non-allergic causes
Most cases of hives lasting less than six weeks (acute urticaria) are the result of an allergic trigger. Chronic urticaria (hives lasting longer than six weeks) is rarely due to an allergy. SKINIPEDIA, your Skin Encyclopedia
