You have been caring for a 50-year-old man with chronic lower back pain for a while now. As you review his medications, you notice that he has been taking regular paracetamol, PRN NSAIDs, and oral morphine. He is currently taking a total of 120mg of morphine within 24 hours, but he is uncertain if it has ever been effective and requests an increase in dosage. What would be the most appropriate next step in managing his pain?
