Chest pain or breast pain when you are angry or have mood swings is relatively common in clinical practice, because mood swings can easily cause excessive excitation of the vagus nerve, which may result in increased heart rate or poor blood supply to the heart muscle, etc. This situation can lead to chest pain and severe angina. In addition, it is also common for some women to experience breast pain, as mastopexy is an endocrine disorder, which can easily cause endocrine imbalance in the body during mood swings, causing an imbalance in the secretion of estrogen and progesterone in the body, triggering a gradual increase in mastopexy, so that breast pain will gradually increase during mood swings. Therefore, patients with heart disease or breast hyperplasia should try to keep their emotions calm and avoid aggravation of the disease when they are overly emotional.
