Small nodules in the lungs are an imaging diagnosis and most do not cause a cough. However, there are many diseases that can cause a nodule-like presentation in the lungs that can have coughing symptoms. Pulmonary nodules are imaging images of nodular density shadows in the lungs. Most of the lung nodules have no clinical symptoms and are usually detected by physical examination. Since most of the lung nodules grow within the lung tissue and rarely irritate the airways, most of the lung nodules do not cause cough. However, there are many diseases that can form nodule-like manifestations in the lungs, including infectious inflammation of the lungs, tuberculosis balls, and fungal infections, which may appear to have symptoms of coughing. When you find small nodules in the lungs, you should go to a regular hospital in time to get a clear diagnosis and targeted treatment.
