Swollen toe – see a shrink.
As for why G-d created podiatrists: Podiatry school teaches the same basic medicine as medical and dental schools, in the first 2 years. They then focus on clinical treatment of feet, whereas medical school in the last 2 years focuses on clinical treatment of everything above the feet, and dental school in the last 2 years focus on teeth, gums and the bones they are anchored in.
Orthopedists treat bones and muscles, but podiatrists treat foot ailments that include infections, skin diseases, neurological problems and other stuff I know nothing about.
