Hi, Your daughter may be having acute urticaria. There may be some cause. Most commonly dietary factors are responsible. Kindly avoid brinjal,tomato, drumstick,guvarfali,lady s finger,curd,cow milk,nonveg,eggs,fermented food ..etc. sometime internal cause mostly infection anywhere in body may be responsible for acute urticaria. Short course of antibiotics may be given. For control of urticaria, I would suggest.. - short and tappering course of steroid - antihistaminics like fexofenadine - apply calamine lotion on hives - avoid soap bath - avoid contact with dusts,wool,cosmetics,pollens..etc I hope this would help you... Take treatment under guidance of your nearby dermatologist. Thanks. Dr. Ilyas Patel MD
