Lung diseases may lead to joint pain, and the causes of the corresponding conditions mainly include pulmonary hypertrophic bone disease, tuberculosis, lung cancer bone metastasis and so on. 1. Pulmonary hypertrophic bone disease: It is mainly due to the secretion of hormone level caused by lung diseases, which further causes osteophytes, periosteal hypertrophy, osteoarthritis formation and joint pain. 2. Tuberculosis: some patients with tuberculosis can sometimes be infected with osteoarticular tuberculosis, leading to joint pain caused by fluid accumulation in the joint cavity. 3. Lung cancer bone metastasis: poor control of lung cancer further leads to the formation of bone metastasis tumor, which will damage the bone quality and cause obvious pain and discomfort. If you have obvious lung disease and accompanied by obvious joint pain, you need to consult a doctor in time, diagnose the specific cause of disease through clinical examination, and carry out standardized treatment under the guidance of clinician to avoid delay of the condition.
