There are no nociceptors in the lungs.
There are no nociceptors in the lungs, but there are nociceptors in the wall pleura, and when the lung lesion is only in the lungs, the patient usually has no pain. Chest pain is usually indicative of pleural involvement. Common causes of chest pain include inflammation and tumors.
For example, when the patient suffers from pneumonia and the inflammation does not affect the pleura or combined with pleural effusion, there is no pain, when it affects the pleura or combined with pleural effusion, the patient will have pain, for example, when peripheral lung cancer does not involve the pleura, there is no sensation of chest pain, and when chest pain occurs, it often suggests that the tumor invades the pleura.
Since there is no pain nerve in lung, early lung cancer is often found through physical examination, and occasionally chest discomfort is found in medical consultation. When chest discomfort occurs, it is necessary to go to regular hospitals in time to avoid delaying the condition.
