Chest pain is one of the common symptoms of pulmonary tuberculosis. The lung tissue has no nociceptive nerves, so the lung itself is not diseased and does not cause chest pain. The causes of chest pain in patients with tuberculosis are: 1. When tuberculosis lesions affect the pleura or when tuberculous pleurisy occurs, there can be chest pain. 2, chest wall tuberculosis or rib tuberculosis: patients with pulmonary tuberculosis can have chest pain when they are complicated by chest wall tuberculosis or rib tuberculosis. 3.Complications of tuberculosis: Patients with tuberculosis complicated by spontaneous pneumothorax and pulmonary embolism can also cause chest pain. How long will the chest pain last in TB patients? Many patients often ask this question. The chest pain in TB patients, especially in patients with pleurisy, will last for a period of time, starting with more intense pain and shorter intervals; as the condition improves, the pain intervals will become longer and longer until it disappears. Of course, the pain in individual patients can last for more than several years.
