Headaches, nausea, and breast pain may be related to autonomic dysfunction and cardiac neurosis. It is important to rest well, ensure sufficient sleep, and further exclude cardiovascular diseases, myocardial ischemia, myocardial infarction, and insufficient cardiac blood supply, which can also cause headaches, nausea, breast pain, cerebral infarction, cerebral hemorrhage, insufficient cerebral arterial blood supply, and cerebral vascular stenosis. These conditions can also trigger migraines and ischemic hypoxic changes in cerebrovascular health, causing headaches, nausea, and breast pain. Blood pressure and blood sugar should be monitored, and blood pressure should be actively controlled to prevent hypertensive encephalopathy.
