She denies fever, nausea, vomiting, and recent travel - she has never had any prior lesions like this in the past. She admits to going to a party where she used a hot tub 2 weeks ago. Temperature is 98.1°F (36.7°C), blood pressure is 132/75 mmHg, pulse is 76/min, and respirations are 14/min. Both axillae have short, 2-mm hairs, and lack lymphadenopathy. Inspection of the right axillae reveals multiple lesions similar to Figure A. The lesions are mildly tender to palpation. Which of the following is the treatment of choice for the patient's condition?
