A 16-year-old girl presents with headache and a burning sensation over the right side of her face for the past three days. She also reports feeling ‘a little off-balance’. This morning, her mother noticed a new rash in the girl’s right ear.
On examination, clusters of vesicles on an erythematous base are noted in the conchal bowl of the patient’s ear (Figure 1). She has a slight weakness on the same side of the face and is complaining of increasing pain.
