good evening, my son is 6 years old and he has a rash in bw his butt cheeks, that is very sore, that doesn t seem to dry at all (he says it always feels squishy ) and he has pimples on his butt cheek that seem to be spreading. We re going on three days now and it s not getting better. I m going to the doctor tomorrow with him but was wondering if you could give me some comfort in knowing what it COULD be? Thank you so much!
