Mild lactational mastitis can be treated with physical therapy, such as hot compresses, acupressure, and massage to expel milk; non-lactational mastitis can be treated with anti-inflammatory drugs or surgical excision. Mastitis is divided into lactating mastitis and non-lactating mastitis. Lactating mastitis is mostly caused by milk stagnation and secondary bacterial infection. Patients with mild symptoms can use hot compresses with towels, microwave treatment of the breast, massage and acupressure to promote milk discharge and dissipation of the inflammation. At the same time, a breast pump should be used to drain the milk to avoid worsening of the inflammation. The cause of non-lactating mastitis is not clear, and may be related to blocked milk ducts, infection, smoking, and breast trauma. Patients with mild symptoms can use drugs such as metronidazole, benzathine sodium, cefradine, etc. for anti-infection treatment to control the inflammatory response in addition to the physical therapy used above. If a patient is found to have mastitis, it is recommended that the patient should seek timely medical treatment and choose the appropriate treatment under the guidance of the doctor to promote the recovery of the body.
