Subtle: hives can occur as part of an allergy syndrome. people with chronic hives or who have an inborn low threshold for hives have difficulty differentiating simple hives from drug allergy. If the drug reaction is IgE-mediated, or occurs via a similar pathway without IgE, then one would expect additional symptoms other than hives (breathing problem, dizzy, nausea, swelling, headache, etc)
