When you have diabetes, you should actually see a podiatrist like Dr. Cynthia Oberholtzer-Classen on a regular basis to make sure your lower limbs are healthy and head off potential problems. You should have a full foot exam at least once a year to check everything over. You may want to have smaller appointments periodically to take care of calluses, nail problems, or any other minor but important foot care work. If you notice any changes to your feet when you perform your daily checks, have them checked right away to prevent problems from getting worse. If you develop an ulcer, get emergency care for it within 24 hours.
