A 72-year-old man with osteoarthritis affecting his left shoulder presents for follow-up. He is currently on regular co-codamol 30/500 for pain relief and takes oral ibuprofen as needed. The patient has been experiencing shoulder problems for several years and has had to increase his pain medication to manage his symptoms. He has also tried using heat and cold packs and has purchased a TENS machine. Despite these interventions, he continues to experience significant daily pain and reduced function of his left arm due to restricted shoulder movement. The patient is hesitant to pursue surgical intervention. What would be an appropriate course of action?
