Help Please. My 5 yr old broke out in hives for the first time 11 days ago, they seem to get worst rather then better. she has them in most of her body including swelling of hands, fingers, toes, lips, and around eyes. They eventually fade away and appear in different areas almost immediately. She took oral steroids for 6 days, and steroid shot 3 days ago. She takes benadryl , zyrtec, advair, and singular every day. She is asthmatic & allergic to milk protein & soy. She had a piece of pizza the day she broke out, but the doctor believed she had overcome the allergy since she was born. So I gave her milk products gradually. Can that cause hives for this long? Could she possibly be allergic to something else? Her hive are horrible even in her private areas and itch very much so. Please help...
