Paying close attention to your feet, primarily by inspecting them twice a day, is the key to preventing serious problems. Once an infection becomes deep-seated, or gets into the bone, you will usually need surgery in addition to antibiotics. Unexplained temperature rise or fevers coupled with open sores or blisters on your feet may signal an infection. Other warning signs may include too much sugar in the urine, or blood sugar that is difficult to control and requires a higher insulin dosage. Again, inspect your feet regularly to prevent serious problems.
Good care requires daily vigilance.
Close visual inspection must substitute for the feeling you have lost in your feet. Look for reddened skin, sores, blisters, inflamed nails, bony prominences, and changes in the shape of your foot. If you have poor vision, you may find a magnifying glass helpful. Most practically, have a friend or family member inspect your feet regularly. Wash your feet in lukewarm water, never hot.
