My brother (who would have been Trump’s age now) had a draft deferment because of bone spurs. We were certainly not rich. It was the recruiting office that would not accept him.
“Heel spurs cause local foot pain, tenderness, and sometimes swelling. This can lead to difficulty walking due to pain at the bottom of the foot with weight-bearing. Sometimes there is accompanying inflammation of the entire bottom of the foot (plantar fasciitis) when the heel spur occurs in the bottom of the heel bone. Occasionally, bone spurs in this location are a result of inflammatory arthritis, such as from reactive arthritis, ankylosing spondylitis, or diffuse idiopathic skeletal hyperostosis (DISH or Forrestier’s disease).”
A good friend had to retire early from the police department because of bone spurs.
