A 47-year-old man presented with right-sided facial pain that started 2 years prior. He described the pain as extremely intense, stabbing along the right jaw, lasting 5–60 seconds. This pain was exacerbated by chewing, and to a lesser degree, by brushing his teeth. The pain was so intense that he avoided eating when possible, leading to a 20-pound weight loss. When he did eat, he would try to chew on the left side of his mouth. Around the onset of these symptoms, he also noticed a persistent numbness and burning extending from the right lower earlobe to the lateral angle of the jaw that was exacerbated by turning his head to the right.
