If lung cancer patients have pain in the clavicle area, the following reasons are generally considered: 1. lung cancer appears in the location of lung tip and supraspinal groove, and the lesion stimulates the local pleura, causing nerve pain in the pleural receptors because of its proximity to the clavicle, so sometimes the pain is felt in the clavicle. 2. bone metastasis appears in the tumor and metastasizes to the clavicle, and this metastatic bone pain is continuous and sore. This kind of metastatic bone pain is persistent and sore, which is not effective after physical therapy and other treatments, and in serious cases, pathological fracture may occur. If you want to know which kind of pain is caused, you must go to hospital for further examination.
