Parenthetically, the children seem to break out usually after they go outside in the fairly cool autumn air. What do you think we should do. Currently, all of us are treating with Benadryl. Thanks so much.
Hives are an outward sign of a whole-body hypersensitivity reaction.
Wheals or welts come and go on the skin or mucous membranes, and may itch intensely. Each typically has a whitish, raised patch of skin surrounded by a reddish halo. The welts may be tiny or large, and may be all over the body or confined to one area. The individual welts often disappear quickly, and are usually gone within 48 hours, although new ones may continue to appear for quite some time. Hives occur when the body's capillaries and tiny veins get leaky.
