CAREER AS A PODIATRIST WHAT PODIATRISTS DO PEOPLE RELY ON THEIR FEET FOR INDEPENDENCE AT ALL AGES AND OFTEN TAKE FOR granted how much they depend on them to get through every aspect of the day. Those who are on their feet too much often punish them with overuse. Podiatric physicians care for patients of all ages. The most common types of foot disorders they treat include: Bunions A bunion is an enlargement of the joint at the base of the big toe that forms when the bone or tissue at the big toe joint moves out of place. Nail problems Ingrown toenails are the most common nail problem and can lead to irritation, pain and swelling.
