What are the symptoms after suffering from pulmonary nodules? Is lung nodule lung cancer? The symptoms of pulmonary nodules depend on the nature of the nodules. Benign lung tumors generally have no symptoms; Acute sarcoidosis has symptoms such as arthritis, erythema nodosum and fever. Subacute and chronic sarcoidosis may have symptoms such as cough, chest pain and dyspnea. Inflammatory pseudotumor may have symptoms such as cough and expectoration; Early lung cancer, especially peripheral lung cancer, is often asymptomatic.

Benign lung tumor: generally asymptomatic, often found in chest X-ray examination. Sarcoidosis: Acute sarcoidosis often includes arthritis and erythema nodosum, accompanied by fever and muscle pain. The clinical manifestations of subacute and chronic sarcoidosis are hidden, 30% ~ 50% have cough, chest pain or dyspnea, and 20% have airway hyperresponsiveness or wheezing. Inflammatory pseudotumor: Patients may have cough, expectoration, low fever, and occasionally blood in sputum. Lung cancer: Early lung cancer, especially peripheral lung cancer, is often asymptomatic, and most of them are found during chest X-ray or chest CT examination. With the development of tumor, different symptoms will appear. Common clinical symptoms include cough, bloody sputum, chest pain, fever and shortness of breath. The most common symptom is cough, often irritating cough. Late invasion of recurrent laryngeal nerve causes hoarseness. Cancer invades the pleura and chest wall, causing persistent severe chest pain.
