I stopped breastfeeding 2 weeks ago but my breast still has hard lump . when will it go away?

Engorgement: It takes up to 1-2 months for the engorgement to completely subside. Try applying warm compresses and massage gently. You can also try expressing some milk to relieve the fullness, and use OTC Pain relievers for pain. If your breast tissue becomes red and warm and the pain increases you may have a breast infection called Mastitis. You will need to see a Dr for treatment.
