A 75-year-old man with a history of metastatic lung cancer presents with severe bony pain. Despite being treated with increasing doses of opioids as an outpatient, he now reports experiencing intense pain in his right shoulder that worsens with movement. This pain is distinct from the metastatic bone pain he has been experiencing in his lower limbs. There is no history of trauma. What would be the most suitable course of action to take next?
