My daughter has been on an antibiotic for about 4 days for an ear infection. since then, i’ve noticed small red bumps (like pimples) on her rear, then it started spreading down the back of her legs. her BM’s have been smelling quite foul (sorry), and think that may be from the antibiotic. i thought at first that the rash was from the BM and the antibiotic, but now it’s creeping down the back of her leg. i haven’t changed her detergent or bath soap, and i haven’t fed her anything new or unusual. i’m going to check her tomorrow morning when she wakes up and if it’s still there or worse, i’ll call her doctor, but i was hoping to get some input from anyone who might have an idea of what this could be from. thanks!
