Initial concern had been that this neurological phenomenon was as a result of complications of his chronic pain intervention. Despite an essentially normal neurological examination and dedicated battery of neurological imaging and special testing, no cause was identified. Over a 7-day period of in-patient admission and physical rehabilitation symptoms resolved entirely. In the course of the workup for this episode, it was suggested that the phenomenon was the result of a side effect of dexamfetamine, an agent that had been prescribed for the patient by his neurologist for treatment of his narcolepsy. On the back of this episode, this treatment was discontinued by his neurologist following an outpatient consultation. Subsequent repeated SIJ injections were entirely uneventful and the patient experienced no further occurrences of this phenomenon.展开更多
