May come and go...: Hives may come and go for weeks. It also depends on what caused them in the first place and whether the offending agent has been removed from her environment (ie, her diet, what she wears...). Once you develop an allergic reaction that causes the body to react, histamine, a chemical is released, and causes the hives. This reaction can go on for weeks.
