It's February thirteenth, and on this day in 1967… Elvis Presley was spending so much time on horseback at his beloved Circle G Ranch in Mississippi that he developed painful saddle sores. With his regular doctor unavailable, Elvis turned to an old friend for help—George Klein, his buddy since high school. Klein’s girlfriend, Barbara Little, worked at a Memphis medical office and arranged for Dr. George Nichopoulos to visit the ranch. That visit marked the beginning of a significant and lasting relationship. Dr. Nichopoulos—better known as "Dr. Nick"—would go on to become Elvis’s personal physician for the rest of his life.
