<unk>  localized on the underside of the breast, with a large area of inflammation. Lactation<unk>  usually affects only one breast and the symptoms can develop quickly. The signs and symptoms usually appear suddenly and they include: * Breast tenderness or warmth to the touch * General malaise or feeling ill * Swelling of the breast * Pain or a burning sensation continuously or while breast-feeding * Skin redness, often in a wedge-shaped pattern * Fever of 101 F (38.3 C) or greater * The affected breast can then start to appear lumpy and red. Some women may also experience flu-like symptoms such as: * Aches * Shivering and chills * Feeling anxious or stressed * Fatigue Contact should be made with a health care provider with special breastfeeding competence as soon as the patient recognizes the combination of signs and symptoms. Most of the women first experience the flu-like symptoms and just after they may notice a sore red area on the breast. Also, women should seek medical care if they notice any abnormal discharge from the nipples, if breast pain is making it difficult to function each day, or they have prolonged, unexplained breast pain. Breast abscess A breast abscess is a collection of pus that develops in the breast with various causes. During lactation, breast abscess develops only rarely, most sources cite about 0.4–0.5% of breastfeeding women. Known risk factors are age over 30, primiparous and late delivery. No correlation was found with smoking status; however, this may be in part because far fewer smoking women choose to breastfeed. Antibiotics were not shown effective in prevention of lactation abscess but are useful to treat a secondary infection (see the section on the treatment of breast abscess in this article). Keratinizing squamous metaplasia of lactiferous ducts may play a similar role in the pathogenesis of nonpuerperal subareolar abscess.
