Hives are small, red, itchy swellings on the skin. They arise quickly and can last up to 48 hours. They appear in clusters which disappear as another cluster develops. Foods like chocolate, nuts, tomatoes, and berries are common causes of hives. Certain drugs such as aspirin, penicillin, and sulfa may cause hives, as well.
Some people get hives simply by rubbing or scratching their skin.
No permanent cure exists for skin reactions. It is best to try and avoid the causes. It may help to change to hypoallergenic and fragrance free products. If contact dermatitis, eczema or hives do occur, they can often be treated with over the counter antihistamines such as Benadryl. If this does not help or if the situation occurs again, see your healthcare provider.
