Chest pain symptoms in patients with tuberculosis may be caused by lesions involving the pleura or intercostal nerves, causing pneumothorax and other reasons. Tuberculosis patients with tuberculosis spread to the chest cavity due to various reasons, resulting in tuberculous pleurisy, or the involvement of intercostal nerves resulting in intercostal neuritis, will appear in the left chest pain, the pain is usually more persistent, in tuberculous pleurisy or intercostal neuritis after the cure, chest pain can not be completely disappeared, but generally symptomatic analgesia, the chest pain will be relieved. If the pneumothorax is formed due to alveolar rupture, there will also be chest pain, chest tightness and even dyspnea. If it is a small amount of pneumothorax, the symptoms can be relieved in a week or so while undergoing active anti-tuberculosis treatment. If the pneumothorax is medium to large in number, closed chest drainage will be needed and the chest pain will be relieved quickly. If the condition is serious enough to require surgical treatment, the chest pain can be relieved gradually after the lesion is relieved, but the time needed is usually longer, and it may take from 1 month to 3 months.
