Hello,
Since your daughter is a child, she needs to take some antihistaminic like Benadryl or Claritin and apply some calamine lotion on the bumps which helps in soothing the skin. She may also need topical steroids and for their prescription, I suggest you to consult a dermatologist soon and get it evaluated.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
