Hello! The gynecologist said I have erosion, but it's small. She says you shouldn't stimulate while breastfeeding. I also have inflammation, we will treat it with ointments and then see about the erosion. Has anyone had erosion while breastfeeding? How were they treated and was it painful to stimulate? I'm scared because of the word "stimulate" ?
