As near as I can tell from what has been made public, the the president’s “routine” medical exam was not only unscheduled, but was actually quite a surprise to the staff at Walter Reed Medical Center.
It’s possible that he might have met the catastrophic cap on his medical insurance and wanted to get his physical done without having to pay a copay or a deductible. Many people are frugal like that.
His physician wrote a memo explaining that the exam was not publicized because of “scheduling uncertainties.” In other words, they had to fit the President of the United States in to their schedule.
“I’m sorry, but we’ve got a sprained ankle from a soccer game and a bloody nose to deal with. Tell the President to take two acetaminophen and call us in the morning.”
Coincidentally, the doctor’s memo made no mention of heel spurs.
