why are my nipples sore

Sore nipples can be caused by a variety of factors including hormonal changes, friction or chafing (especially from clothing or during exercise), infections (such as yeast infections or bacterial infections), skin conditions like eczema or dermatitis, breastfeeding challenges, or even irritation from soaps, detergents, or fabrics. Hormonal fluctuations around menstruation, pregnancy, or breastfeeding often lead to nipple tenderness. In rare cases, nipple soreness could be a sign of more serious conditions such as Paget’s disease or breast cancer, especially if accompanied by other symptoms like discharge, lumps, or changes in nipple appearance. If sore nipples persist, worsen, or come with concerning symptoms, it's important to see a healthcare provider for evaluation and appropriate treatment.
