MSFinals-2656

A 79-year-old woman presents to her GP with complaints of worsening pain in her left knee for the past 6 months. The pain is more pronounced during the day and subsides at night or when she is at rest. She experiences increased stiffness in the morning, which takes around 15 minutes to resolve. She denies any joint problems in the past and is currently taking amlodipine for hypertension, which is well controlled. She has no known drug allergies. What is the most suitable initial management for this patient?
