Breast Itching and Sensitivity

I asked Euria (AI assistant from Infomaniak) why I was getting very itchy nipples and very sensitive breasts. This is an edited copy of the response: ItchingThe itch arises from several overlapping mechanisms: Mechanical stretch.Proliferating glandular tissue behind the nipple-areolar complex stretches the overlying skin. This activates mechanosensitive C-fibres (the same unmyelinated nerve fibres that carry the itch sensation), producing a persistent pruritic signal even without any skin pathology. Local inflammatory mediators.Gynaecomastia histologically shows ductal epithelial proliferation with a periductal lymphocytic infiltrate. This low-grade inflammatory milieu releases histamine, prostaglandins, and cytokines (IL-31 in particular) that directly sensitise cutaneous nerve endings. The result is itch without visible rash. Skin changes.Chronic stretching thins and dries the epidermis over the mound, compromising the barrier and making it more reactive to friction, sweat, or…
