In addition to myocardial ischemia, it may also be caused by cardiac neurosis. Pain medication may be given, and a chest X-ray or chest CT examination is needed because patients with pleurisy, especially in the acute phase, may experience pinprick-like pain in the chest, or even pain similar to a knife cut, with restricted deep breathing and coughing. The diagnosis can be confirmed early by CT examination and should be treated actively with anti-infective therapy, as well as a nutritious diet to enhance physical fitness. For specific infections, such as tuberculosis infection, you should go to a specialized hospital for anti-tuberculosis treatment, and pay attention to proper nutrition and high-protein foods during treatment.
