A 52-year-old man presents to the urgent care clinic with a 2-day history of a painful, red rash on his right forearm. He reports the area started as a small red spot that has expanded. He denies any recent trauma. States he is a factory worker. Vital signs: Temperature 99.2F, blood pressure 132/78 mmHg, heart rate 88 bpm, RR 18bpm, O2 99% on room air. Physical examination reveals a bright red, indurated plaque with a sharply demarcated, raised border on the right forearm. The area is warm and tender to palpation. There is no crepitus, fluctuance, or purulent drainage. No lymphangitic streaking is noted, but there is mild right axillary lymphadenopathy. What is the most appropriate treatment for this patient?
