Pneumonia can lead to symptoms of chest pain. In severe cases, pneumonia irritates the pleura and can lead to symptoms of chest pain and sometimes pleural effusion. When patients are diagnosed with pneumonia, they should be treated actively. They need to improve relevant examinations, assess the possible infection-causing bacteria, and take appropriate treatment according to the causative bacteria, such as anti-infection, anti-virus, and anti-Atypical pathogenic bacteria treatment. Patients with pulmonary tuberculosis will usually show symptoms of tuberculosis toxicity such as forceful fever, weakness, night sweats and emaciation, while patients with lung malignant tumors will show clinical manifestations such as coughing up blood, fever and emaciation.
