Chest pain is not necessarily a sign of menstruation and should not be judged simply by that. Before menstruation, some women may experience chest swelling, abnormal emotions, leucorrhea, lower abdominal cramps, and lower back pain, but the vast majority of women do not have obvious symptoms before menstruation. Usually, menstruation is very regular, and premenstrual period is often characterized by bilateral breast swelling and pain, which recently conforms to the previous sensation and may be the arrival of menstruation. Normally, there are no obvious symptoms of menstruation, or it is not yet menstrual. The occurrence of chest pain cannot be taken seriously, and there are many causes of chest pain, such as coronary heart disease, breast enlargement, breast cancer, intercostal neuritis, lung tumor, etc. According to the severity of the pain and other symptoms accompanying the diagnosis, it is best to go to the hospital for an examination so as not to delay the treatment. Pay attention to rest, don’t get cold in the abdomen, eat less cold food, as well as don’t get angry during menstruation to avoid triggering chest pain.
