Q. A 55-year-old man who has a medical history of hyperlipidemia comes to the clinic for a routine follow-up visit. He has been consistently taking statin medication for the past 6 months. During the visit, he reports that he has been dealing with widespread muscle soreness lately. His temperature is 98.6°F (37°C), pulse is 80 beats per minute, blood pressure is 120/84 mmHg and respiratory rate is 14 per minute. On physical examination, muscle tenderness, particularly in the calves, is observed. Muscle strength and reflexes are normal. What is the best next step in his management?
