Question: can yeast infection cause sore nipples?
Answer: IS THRUSH CAUSING MY SORE NIPPLES? Persistent nipple pain in the early weeks of breastfeeding, or nipple pain that appears after several weeks or months of pain-free nursing, may be caused by thrush, which is a yeast infection of the nipples. Thrush is caused by a yeast fungus, usually Candida albicans.
