Dr. August Bier noted this adverse effect in 1898 in the first patient to undergo successful spinal anesthesia, a 34-year-old laborer undergoing resection of an ulceration of the foot. Bier observed: “Two hours after the operation his back and left leg became painful and the patient vomited and complained of severe headache. The pain and vomiting soon ceased, but headache was still present the next day.”1
