Chest pain when sneezing may be related to trauma, or it may be caused by intercostal neuralgia or lung disease. 1. Trauma: If the chest area is squeezed or hit due to an accidental injury, resulting in damage to the chest wall, chest pain may occur when sneezing. It is mostly considered that it may be caused by the large amplitude of movement when sneezing, resulting in the violent shock to the injured chest. 2. Intercostal neuralgia: usually caused by thoracic spine tumor, herpes zoster and other disease factors, which can lead to pain in the patient’s intercostal innervated area, especially when sneezing, which is easy to lead to strong shock to the intercostal area, which may cause chest pain. 3. Lung diseases: common in tuberculosis, pneumothorax, pneumonia and other diseases, may lead to chest pain when the patient sneezes, and it is considered that it may be caused by the stimulation of the chest when sneezing. Chest pain when sneezing may also be caused by other reasons. If accompanied by obvious discomfort, you should consult a doctor as soon as possible, and give targeted treatment after a clear diagnosis of the cause.
