Thanks for your question on Healthcare Magic. I can understand your concern. Breast pain during feeding is very common. Mostly it is due to teething, bitting or sucking hard by the baby. So first rule out this causes. Other causes are breast abscess, infection and hormonal imbalance. So get done ultrasound examination of breasts and hormone levels (prolactin, estrogen and progesterone). Treatment should be guided according to the cause. Infection and abscess will need surgical correction. Hormonal imbalance will need hormone pills to regulate hormone levels. Warm water pad on affected areas of breast and simple painkiller like ibuprofen are sufficient for such pain. Hope I have solved your query. I will be happy to help you further. Wishing good health to your wife. Thanks.
