Patients who experience chest pain when they are sad may have cardiac neurosis. Cardiac neurosis is commonly seen in young female patients, and may be caused by patients with chronic mental stress or chronic insomnia or emotional disorders. Patients may experience chest pain, which may be accompanied by chest tightness and panic. The symptoms may worsen when the patient is tired, emotionally excited or strenuously active. In addition, chest pain may also be caused by intercostal neuritis, such as intercostal neuritis caused by cold or viral infection, which may lead to pain along the intercostal nerve distribution area, and the pain may worsen when the patient is tired or active. In addition, patients with viral myocarditis or costochondritis may also experience pain in the chest. Therefore, it is also necessary to take rest, avoid straining, and maintain a calm state of mind, in addition to further examination to clarify the diagnosis and provide targeted treatment according to the cause.
