If the lung nodule is small, it usually does not cause pain. However, if the lung nodule is large or present in a different location, it may cause chest pain when coughing. In general, lung nodules that do not involve the chest are less likely to cause chest pain. However, in the case of a larger lung nodule with symptoms such as coughing, sputum and chest tightness, the pleura will be affected and chest pain will occur. In addition, if the nodule is located at a small distance from the pleura or at the edge of the chest, it is likely to affect the intercostal nerves and the pleura, resulting in chest pain. It is important to note that if symptoms such as lung nodules or chest pain occur, you should consult a doctor in a timely manner and receive scientific and standardized treatment under the doctor’s guidance to prevent the condition from worsening.
