Hi, my daughter is 5 years old and has a rash at her hairline starting from the temple on only the left side of her face. It goes down to her ear and she has flat reddish pimples scattered on her scalp also again only on the left side. I have also noticed a couple pimple like dots on her collar bone area and upper back. We have a appoint at the end of Oct. Can't get in with pediatric dermatologist till then. What could it it be and how should I be treating it till our appointment? Thank you.
