Sedating kids

Because hives fluctuate so much and so fast, it is helpful to bring along a photograph of what the outbreak looked like at its most severe point.Swelling deeper in the skin that may accompany hives is called angioedema.Hives can also develop as a result of sun or cold exposure, infections, excessive perspiration, and emotional stress.

Hives appear when histamine and other compounds are released from cells called mast cells, which are normally found in the skin.Despite the reputation of hives being an "allergic" condition, there is often no obvious connection to any provoking substance.In this situation, random allergy testing is not usually helpful.Occasionally, it may be necessary to limit specific foods or drugs for a time to observe any affect upon the skin condition.Certain systemic diseases and infections may occasionally present in the skin as hives.
