Breasts will swell and hurt after pregnancy. Normally, breast swelling and pain mostly occur in early pregnancy, and the swelling and pain will gradually decrease as the body hormone levels stabilize in mid-pregnancy. Breast swelling and pain is due to increased estrogen levels in the early stages of pregnancy, thickening of the fat layer and congestion of the breasts, which leads to swollen and painful breasts, as well as raised nodules in the areola. The appearance of breast swelling and pain is also one of the typical symptoms of pregnancy. For more severe breast pain after pregnancy, it can be relieved by hot compresses and massage. Pregnant women should be gentle in caring for their breasts to avoid damaging the nipples. During pregnancy, the color of the areola will deepen and the skin will have pigmentation, which is a normal phenomenon and there is no need to be alarmed.
