Diabetic Foot Ulcer

What are the signs and symptoms of the condition?

Early symptoms of a diabetic foot ulcer include redness of the skin, blistering, and other signs of irritation. In later stages, the person may have an open wound that drains fluid onto socks or bedding. The open wound can then become infected and develop swelling, redness, and drainage of pus. The person may have a fever, and blood sugar levels may be higher than usual.
