If you have a needle-like sensation in your chest, consider the following aspects: First, consider breast diseases, including mastitis, mastopexy, breast trauma and breast lumps. Mastitis refers to the accumulation of large amounts of milk in the breast or bacterial infection caused by breastfeeding women who do not suckle in time or breastfeed. Mastocytosis is common in non-menopausal women and is mainly caused by elevated levels of estrogen in the body. Mastocytosis associated with the menstrual cycle will resolve after menstruation and is not a cause for concern. Breast trauma refers to soft tissue contusions of breast tissue by breast lumps, often with symptoms such as uneven surface skin and discharge. Second, consider having heart disease, such as angina pectoris, myocardial ischemia, etc. Myocardial infarction will have a pinch-like pain sensation.
