Welcome to HCM.
Your daughter would be having acute urticaria
She should be thoroughly investigated.
Some cause might be there...it should be found out.
Dust,pollens,enviornmental pollution,grass..etc or some food like fish, prawns , eggs,peas,banana,curd,fermented food..etc can cause the urticaria.
Oral antihistaminic might control the disease.
If severe, steroid
ma be given.
I hope you got my answer.
