Postpartum breast pain usually indicates acute mastitis, and one can go to the general surgery department of a hospital for treatment. Postpartum mastitis often occurs because the breast ducts are blocked by breast milk that isn't properly expelled, which can also cause breast lumps. In such cases, it is crucial to express the breast milk to facilitate the clearing of the breast ducts. The changes in a woman's breasts after childbirth are very noticeable. The breasts enlarge and produce milk. If there is difficulty in expelling milk, this can lead to breast pain and even the formation of lumps, necessitating a visit to the surgical department of the hospital for examination and treatment.
