Chronic urticaria: Hives lasting longer than 6 wks is known as chronic urticaria, often has no known environmental or food relationship. In most cases, there are no known allergen triggers, but can be brought on by some things like heat, stress, lack of sleep, etc. Rarely due to an underlying condition. Treat with oral antihistamines. May need something stronger if not working. See allergist to further evaluate.
