A podiatrist is a medical specialist who provides treatment and diagnosis of ankle and foot problems. These include bunions, hammertoes, ingrown toenails, corns and calluses, ankle sprains, heel spurs/pain, neuromas, warts, and more. To become a podiatrist, you must complete undergraduate medical school training as well as a graduate school for a doctorate in podiatry. A podiatrist is required to take state and national exams and complete licensing in the state in which they practice.
