Why are my breasts tender sometimes?
Some breast pain is common in the first few weeks after delivery. This “physiologic” pain is related to the normal function of the breast and may be caused by the weight of the breast, the filling with milk, or by let-down pain. Breasts grow during pregnancy. After delivery, breasts contain extra blood and nutrients. Heavier breasts pull on the skin and support structures of the breast and cause pain. This is normal and usually settles within weeks. Supportive clothes such as a firm bra can help. It is also normal to feel fuller before feeds during the early weeks. When milk fills the breast, it stretches the breast tissue, causing pain. This can be eased by massage, cold compresses, and breastfeeding when the baby is hungry. Such pain should not be persistent, increasing, or severe.
