i dont know what else to do

My daughter has an infection inside her right nostril and the smell is really strong...My daughter is 2 years old. she was born 24 weeks premature so she had been on breathing tubes in her nose for 3 1/2 months which collasp her nose. (no bridge) I have gone to the emergancy room, to her doctor and to the ent. she has been on 4 differant antibiotics. the last one she was on killed the smell while on the anitbiotic, but as soon as the antibiotic was finished it came back. i went to the ent on monday and they prescribed her another antibiotic and nothing is working. there is discarge coming out that is irritating her skin. Idk what else to do, i hate to see her in pain and suffering with that smell... can someone help me with what to do next. thank you >email address removed<
