This question has been posted twice by others with no response. Im a 38 year old female, not pregnant and I have a 10 year old. For the last week I have had really painful nipples. It is exactly the same feeling as I had when I was breastfeeding and I had mastitis - engorged breasts and really painful nipples, now it is particularly the left one, confined to the nipple area. I also have breast implants that were done 11 years ago (silicone gel). Further, my nipples are and always have been almost always erect regardless of the weather which I really hate. Does anyone know what could be causing the pain?
