hi my toddler has been complaining of her tummy aching sporaticly during the days for a month now. Her diet or routines have not changed. She also has had a rash on her butt which her ped said looked liked eczema . Well her rash got worse which looked like circular burns & ped finally presrbd mupirocin, rash is a little better but not much. They also prescribed mebendazole for pinworms? Since she s been complaining of tummy aches aslo slight red patch on one of her labias. Do you know what could be the cause od her tummy ache, rash, if this sounds like she needs mebendazole? Checked her anus for worms saw nothing nor in her poop. Thank u so much.
