Q. A 55-year-old female presents to your clinic with complaints of joint pain, swelling and stiffness. She reports that these symptoms have been present for the past 6 months and have been gradually worsening. She also reports fatigue and a low-grade fever. Physical examination reveals synovitis and swelling in multiple joints including her hands, feet, and knees. You also note tenderness and limited range of motion in the affected joints. You order laboratory tests, including a complete blood count, erythrocyte sedimentation rate, and rheumatoid factor test, which are all elevated. A subsequent joint x-ray shows evidence of erosive joint changes consistent with rheumatoid arthritis. Based on the patient's history, physical examination findings, and laboratory results, you make the diagnosis of rheumatoid arthritis. You decide to start her on prednisone to relieve her symptoms. She is also referred to a rheumatologist for further management and to discuss other potential treatment options. You instruct the patient to monitor herself for potential side effects of prednisone. Which of the following is NOT a common side effect of prednisone?
