Pneumoconiosis is a common occupational disease in our country, where workers often face relatively harsh environments with a significant amount of dust pollution. Continuous work in such environments can lead to the development of pneumoconiosis. What symptoms might appear after contracting pneumoconiosis? Common symptoms include coughing, phlegm production, coughing up blood, chest pain, chest tightness, and fatigue. If these symptoms occur at work, and pneumoconiosis is suspected, one should visit the local relevant departments for an occupational disease assessment.
