Hives triggered by sudden stress, heat, cold, sweating and exercise may disappear within an hour. Chronic urticaria from emotional stress, however, may recur often and lead to distress and disability. Hives from emotional stress have signs of redness, itching and burns on the upper chest and neck, swelling of lips or eyelids, or angioedema that affects deeper layers of skin. Hives are often observed in women during premenstrual periods, reports Asthma and Allergy Foundation of America. See a doctor immediately if hives lead to dizziness, wheezing, tightness of the chest, difficulty breathing and swelling.
Hives are diagnosed with a medical history interview and a physical exam. Nonsedating antihistamine medication is available to treat itching, explains Asthma and Allergy Foundation of America. Other treatments include corticosteroids, autoimmune drugs and blood protein controllers. Those suffering from hives may be put on an allergen-elimination diet and keep a diary to keep track of when hives occur. Immediate remedies for hives include cool compresses and bandages; a cool bath; wearing loose, cotton clothing; avoiding emotional stress triggers; and exposure to certain foods, pollen, latex, pet dander and medications.Learn more about Pain & Symptoms
