MSFinals-2802

A 65-year-old woman visits her GP complaining of a persistent headache that has been bothering her for two weeks. The pain is more intense on the right side and is aggravated when she combs her hair. She also experiences discomfort in her jaw when eating. Her neurological and fundoscopy examinations reveal no abnormalities, and she is referred to the emergency department.

Upon admission, the patient is prescribed high-dose oral prednisolone and undergoes a temporal artery biopsy, which yields normal results. What is the next most appropriate course of action for her treatment?
