My 5 year old has a persistent rash in the crooks of both arms. Bright red, bumpy, periodically itchy. The skin in the area appears stretched and shiny. We recently moved from CA to AZ, the change in temperature and humidity has not affected the rash at all. Her dad has issues with eczema, so this would be my first guess. But he is also sensitive to hydrocortisone, which leaves me wondering how to best treat her as I m afraid she will have the same sensitivity.
