The tingling sensation in the breasts during late pregnancy is usually due to hormonal changes in the body and is normal in most cases. Very few pregnant women may experience tingling due to breast enlargement, which requires further examination. During late pregnancy, the levels of estrogen and prolactin in the pregnant woman’s body change drastically, and the increase in prolactin levels in preparation for postpartum lactation may cause hyperplasia of the mammary glands during the period of time, resulting in tingling in the breasts of the mother. There is no need to worry too much about this condition. Tingling sensation in the chest may also be caused by breast hyperplasia, which needs to be confirmed by breast ultrasound examination. Pregnant women should have regular checkups to check their health condition. If abnormal pain occurs, they should go to the hospital immediately to find out the cause of the pain. Symptoms can be relieved by hot compresses and appropriate massage, but care should be taken not to knead excessively to prevent irritation of the hyperplasia area.
