Review Question - QID 212686

A 38-year-old man comes to the clinic for “numbness and tingling” of his hands for the past 2 months. He immigrated from India 6 months ago and did not have health insurance until now. The patient reports a persistent rash that appeared 4 months ago that he attributes to the change in weather in Detroit compared to India. He denies weight loss, fever, chills, chest pain, vision changes, lightheadedness, or weakness. His past medical history is significant for poorly managed diabetes due to lack of health insurance. A physical examination demonstrates patches throughout the skin (Figure A), paresthesia of the distal hands bilaterally, and skin swelling on the left earlobe. What is the most appropriate treatment for this patient?
