Hi, I had gone through your query and understood your concerns. Usually corns heal by themselves or can be managed at home with some remedies. But in Diabetics, its not advisable to do anything at home that too in sucha long term case. So better i advice you to visit local physician or podiatrist for either removal or use of proper antibiotics in their care. Meanwhile cushions to put between the toes; foam or moleskin pads to put over the places where corns form; foam pads with holes in the center (like donuts or bagels), which redistribute pressure around the corn instead of right over it; cushioned insoles to pad your feet and alleviate mechanical pressure. Hope this guides you. For any other queries you can write to us. We will be happy to help you. Thank you. Dr Phanindra Dulipala Diabetologist.
