An 88-year-old woman presents with severe pain in her shoulders, lower back, and both knees which is exacerbated by physical activity, unresolved by acetaminophen, and associated with morning stiffness lasting for around 10 minutes.

Her medical history is significant for an inferior ST-elevation myocardial infarction three years ago, which was managed medically, with atrial fibrillation as a lasting sequel. She also underwent bilateral hip replacement five years ago for severe osteoarthritis.

She is currently on warfarin, metoprolol, enalapril, and rosuvastatin, and has adhered well to her medications. She lives with her eldest daughter and is well-cared for.

A complete blood count is within normal parameters, as is a renal profile, fasting plasma glucose, and ESR.
