Girls, SOS. I need help urgently, my child has staphylococcus since birth and they find it in her nose and stool, we treat it but there's no effect, the phlegm just suffocates her, she gets choked up, it's awful. They prescribe bacteriophages, at free clinics, staphylococcus is not a cause for concern, at paid clinics we treat it but there's no effect. Maybe someone has encountered this, what did they treat, what really helps?
