Hives are characterized as itchy red, raised welts (also known as wheals) on the skin's surface that can spread or join together and form larger areas of raised lesions. They are generally triggered by exposure to an allergen or chemical irritant. They tend to appear suddenly and often disappear equally as suddenly.
Hives are usually an allergic reaction to food, medicine or animals. They can also be triggered by sun exposure, stress, excessive perspiration or other, more serious diseases, such as lupus. Anyone can get hives.Hives can be triggered by multiple factors at the same time. Stress, medication, a food that normally does not make you hive, a hot shower, all coalasce to create the wealt. Hives require an extensive history both medical and environmental to uncover the inciting agent or agents.
There are many over the counter and rx meds to quiet the symptom, but nothing comes close to discovering the cause and eliminating the condition altogether.
