This case report describes a case of a 44-year-old female, who presented with dysmenorrhea and had undergone total abdominal hysterectomy with bilateral salpingectomy and manifested as head titubation which was a conversion reaction. On evaluation, it was revealed that the patient had chronic depression and pain. This case report highlights a rare presentation of FND.
