Neonatal mastitis is inflammation of breast tissue in infants under 2 months. It is usually caused by bacterial infections like Staphylococcus aureus entering through ducts or damaged skin. Symptoms include tender, swollen breasts with discharge and fever. Diagnosis involves examination, imaging, and testing drainage from incisions. Treatment consists of antibiotics, analgesics, and incision/drainage of abscesses along with physiotherapy.
