Hello Doctor, I Am Concerned About My Daughter's Skin Condition.

Hello Doctor, I am concerned about my daughter's skin condition. There was a spot on her leg that was itchy then other spots appeared nearby. The older ones have already healed, but recently, two pus filled blisters randomly appeared near her knee. She has been applying bandaid antiseptic wash, MelaGel and Neosporin. I would like to know what possible diseases match her condition and if there are any possible treatments for it. Can i take a picture and attach it so that you can have a clear picture of it. Thank you.
