  Case Scenario Top


A 19-year-old male presenting with a persistent localized pain in his right shoulder was admitted to our hospital. He reported that the symptom started within 3 months ago when he had a rash with unilateral distribution of grouped vesicles on an erythematous base [Figure 1]a that recovered after 2 weeks [Figure 1]b. He was previously healthy, and his family history was unremarkable and negative for neurological disorders. He stated that he had an episode of varicella (chickenpox) when he was a child. On neurological examination, allodynia and hypersensitivity were observed on his right shoulder.
