With the development of the disease, abscess can be formed within 4 ~ 5 days. The patient's breast may have pulsating pain, and the local skin will be red, swollen or transparent. When the disease progresses, the patient's breast center will become soft, and this pain will continue, making the patient miserable. An abscess can be found in the breast after puncture examination. Sometimes there are several such abscesses, which can be formed at different times. With the continuous development of the disease, the patient's condition will gradually worsen. Abscess will burst out from the skin surface, and milk will involuntarily overflow from the wound. If this happens, women's hospitals can diagnose their condition through gynecological examination.
