There are many reasons for the recent appearance of chest pain: First, patients with insufficient blood supply to the heart and myocardial ischemia can manifest as chest pain, and there are also certain triggering factors, full meals or exertion, mood swings can trigger it, and an electrocardiogram should be performed promptly, which can make a clear diagnosis. Second, some patients belong to breast diseases, such as breast hyperplasia, breast fibroadenoma, or even malignant tumors occurring in the breast, which can manifest as chest breast pain. Patients with benign lesions will have regular pain, while pain due to malignant lesions will gradually worsen, and bloody nipple overflow will also occur. It needs to be combined with a physical examination such as breast color ultrasound, and if necessary, surgical treatment needs to be chosen. Third, a part of patients with cardiac neuropathy will also have chest pain.
