Review Question - QID 214415

A 56-year-old woman presents to the clinic with complaints of leg discomfort for the past 4 months. The patient reports discomfort of both legs especially at night when she sleeps. She describes the sensation as a "tingling" that is sometimes cramping and painful in nature. The sensation is improved when she sits up, moves her legs, and dangles them over her bed. These episodes are not constant, but they have resulted in poor sleep over the past 2 months. Her past medical history is significant for diabetes and hypertension; her last HbA1c 3 months ago was 6.7. She is a 20 pack-year smoker and drinks socially. Family history is significant for heart disease in her father. A physical examination reveals decreased pinprick sensation of the feet bilaterally. What is the most appropriate treatment for this patient’s symptoms?
