A 24-year-old man, who recently received a diagnosis of HIV infection, presents to the emergency department (ED) with a 24-hour history of left ear pain. He saw his doctor the day before the ED visit and was told that everything looked okay and there was no suggestion of ear infection. Today his pain is worse and his ear is now red and swollen. He also feels dizzy and vomited twice as a result. He describes the dizziness as a “spinning” feeling.
