A 65 year old lady attends the GP complaining of bilateral pain and stiffness around the shoulder region and fatigue for several weeks. The stiffness lasts for around an hour after waking and after periods of rest. Systems review is unremarkable, and she has no past medical history of note. Your GP colleague had requested bloods recently and you note raised inflammatory markers, but baseline FBC, renal and liver function are otherwise normal.
Based on the likely diagnosis, what is the next most appropriate step in management?
