Hives Urticaria

Hives or urticaria are generally the result of an allergic reaction although there are also comparatively rarer cases of non allergic reactions.

Hives are itchy red or pink welts that appear on the skin either in clusters or individually scattered. Their appearance can either be as pinpoint rashes or larger wheals that can be several centimeters in diameter. These wheals often have a well defined border and can either be circular in shape or they can form larger patches. In most cases they appear on the trunk and abdomen although they can spread to the arms, legs and back. The individual hive can last for a few hours or a few days before it fades away completely and new ones appear in different areas. Although the skin is raised, it is rarely scabbed. Hives are extremely uncomfortable as they can cause intense itching or stinging. Repeated or vigorous scratching can cause the skin to tear and thereby get infected.

Hives are divided into two main types depending on the amount of time it takes to clear. Acute urticaria generally appears a few minutes after contact with an allergen. They generally do not last for more than 6 weeks. Food allergies often fall under this category. The most common food allergies are caused by shellfish and nuts although soy, cow’s milk, cheese, eggs and wheat too can cause an allergic reaction. Exposure to certain bacteria like streptococcus too can cause this type of hives.

Chronic urticaria on the other hand, can persist for months and can even take years to clear completely. This type of urticaria is most commonly caused by an autoimmune condition. Acute viral infection, extreme temperatures and sunlight too can cause this type of urticaria.

There are several other causes of hives such as an allergy to a certain medication, most commonly sulphonylurea glimepiride - an anti-diabetic drug. Allergies to other medications like penicillin and various anticonvulsants are not uncommon. There are also allergies that are triggered by high stress levels. This allergic reaction is often seen in people suffering from posttraumatic stress.

There are several treatments that are available to counteract the discomfort of an allergic reaction. Many of these drugs, however, cause drowsiness and some of them have even been linked to heart problems. There are several natural treatments to ease discomfort. Soaked oatmeal added to a tub can ease itching and soothe inflamed skin. People with an allergic reaction often find it tough to get sound sleep due to their discomfort. Dab a little lavender oil to a piece of clean linen and place it near the headboard of your bed. Lavender oil has a very pleasant aroma that soothes the senses and promotes sleep. The skin should be kept well moisturized at all times. It is better to use a non perfumed anti-bacterial moisturizer to keep the skin moisturized and protected from infection.
