You are seeing a 20-year-old female in a GP setting who is complaining of earache, which has been present for the past couple of days. On examination you note that the ear canal is red and swollen. You do some observations and they are as follows: BP 121/83, HR 87, RR 16, O2 saturations 100% on room air and a temperature of 38.3 degrees. What is the most appropriate next step in management?
