Many patients with pneumoconiosis will have chest pain, but none of the causes can be determined at this time, because each person behaves differently. It is believed that: first, after pneumoconiosis, some of them may involve the pleura, especially asbestosis can cause pleurisy or pleural adhesions, pleural hypertrophy, then after pleural hypertrophy and adhesions, we may have pain due to pleural pulling when we inhale; second, our pneumoconiosis causes a large mass-like shadow on the lung, which can lead to pulmonary pulling, contracture or uneven inflation of the lung, resulting in Localized pressure increases causing pneumomediastinum. This is one of the causes of pain, but not every pneumoconiosis patient will have chest pain, and even in pneumoconiosis patients, the location of the pain is different, sometimes it may be in this area, sometimes it may be in another area, so whether this pain is directly related to pneumoconiosis itself is not very certain.
