Urticaria or hives are red, itchy, swollen bumps on the skin that appear suddenly.
Types of Hives
Cholinergic Urticaria - hives that appear during an activity that raises the body temperature
Chronic Urticaria - hives that continue frequently for longer than 4 weeks
Cold-Induced Hives - occur after exposure to cold wind or water
Solar Hives - caused by exposure to sunlight or sunlamp
Exercise-Induced Hives - occurs during or after exercise
Causes
Hives are often triggered by drug and food allergies. However, some types of hives are not triggered by an allergy at all.
Prevention and Treatment
Antihistamines are used to treat recurrent hives and relieve symptoms. If food, drug or another allergens cause hives, avoidance is the only method of treatment.
