Talk to Gynecologist on Breast Pain

AOA, I am just posting for my wife who is having severe breast pain, already consulted with her Gynaecologist and she prescribed only a pain killer (Brexin 20mg) and said that it's just because of breast feeding. But she's still having pain in the night and it's severe. Can anyone help on this to whom should she consult other than Gynecologist.
