Girls, hi! We got another rash again, specifically, pimples appeared near the mouth, small and like they're from rubbing. When he squeezes with his fist and rubs it, it turns red. It's impossible to get in touch with the pediatrician. If we talk about the main point, we just recently treated eczema with Fenistil for oil and Johnson's powder. It has been only 1.5 weeks since that incident. Can we give him Fenistil for 2-3 days now?
