My daughter is 4years 2month old...she suddenly started having hives on her body...doctor called this urticaria..gave atarax for 5 to 7days...6month back also she had urticaria all over her body...though this time less severe...my question is why she is having urticaria again n again..?should I give atarax to my kid...again? I did not give her atarax this time thinking she is having less hives than before...will urticaria go away on its own or I need to give atarax? Why she is having this again n again...can there be any underlined disease...behind it...should need to do any test for that ..plz help...I shall be grateful to you..
