Since diabetes can lead to nerve damage, people with diabetes might not be able to feel a cut or a blister on their feet. With poor circulation, the cut or blister takes longer to heal and can become infected.
The treatment you need can vary depending on what the problem is. You may need surgery, crutches, rest, or treatment for an infection.
One major diabetic foot issue is Charcot foot, where the bones in the foot start to break down and your foot changes shape. Surgery may be needed to treat this condition.
