In addition, acute mastitis can also appear as a symptom of breast pain and localized redness and swelling, which requires prompt medical treatment at the hospital. If a lump in the breast is touched, you need to go to the hospital for treatment. In either case, it is recommended to go to the hospital for treatment.
