why are my nipples sensitive

Nipple sensitivity can be caused by a variety of factors including hormonal changes, friction or chafing, skin conditions, infections, allergies, pregnancy, breastfeeding, or even certain medications. Sensitivity is often due to changes in hormone levels during menstrual cycles or pregnancy, causing the breast tissue and nipples to swell and become tender. Physical irritation from clothing, exercise, or sexual activity can also lead to soreness and sensitivity. Additionally, skin conditions like eczema or allergic reactions to soaps, lotions, or detergents may result in nipple discomfort. In rare cases, sensitivity might indicate an infection or more serious conditions such as Paget’s disease of the breast, so persistent or severe pain should be evaluated by a healthcare professional.
