My sister has had a persistent bacterial infection since 2 months postpartum. It has now been 4 months of this infection. She has went to her dr twice and had a VE each time and confirmed it is a bacterial infection. They gave her Metro gel cream, whatever that is, both times. They won't give her anything else because she is nursing and the dr told her that if the cream doesn't work this time that they are gonna recommend her stop nursing for a week so that she can take something stronger. She has no plans of stopping nursing for any period of time but doesn't know what to do about the persistent itching and odor. I told her to start a probiotic but other than that I don't know what to suggest. Ideas please?
