Diabetes can cause reduced blood circulation or nerve damage to your feet meaning you might not realise you have an injury or ulcer.
It’s a good idea to check your feet every day. Wash them carefully in warm, soapy water and check your skin for cuts, scrapes or ulcers. Use a cream to moisturise if needed but do not apply it between your toes. Cut your nails regularly. You may need help from a podiatrist to ensure you are cutting your nails correctly to avoid ingrown toenails or other infection.
Good footwear will help your feet stay healthy. Shoes and socks/stockings that fit properly will not cause blisters or calluses that may become infected. Seek the advice on proper footwear from an expert podiatrist.
