John F. Kennedy, our nation's youngest president, had a host of medical conditions that plagued him since childhood. Here, Kennedy entertains Alberto Franco Nogueira, the foreign minister of Portugal, while sitting in the rocking chair his doctor ordered to support his excruciatingly painful lower back. The photo was taken November 7, 1963, just two weeks before he was assassinated.
Despite being turned down by both the Army and Navy due to his bad back and other medical issues, Kennedy was able to get into the Navy with the help of his father, Joe Kennedy.

Accompanied by his wife, Jackie, Kennedy leaves the hospital to be with family for the holidays two months after the 1954 spinal fusion surgery. It took that long to overcome the complications.
In this image taken in his Senate office in January 1955, Kennedy is suffering from ramifications of his October 1954 spinal implant designed to fuse his spine and relieve his pain. An infection kept the incision from healing, creating an "open, gaping ... hole," according to his speechwriter. The implant was removed in February.
In June 1961, Kennedy still used crutches to walk from his car to a ramp to board the presidential yacht Honey Fitz for a cruise down the Potomac River with Japanese Prime Minister Hayato Ikeda. When he reached the ramp, he disc
