Diabetic foot ulcers are a common complication of poorly controlled diabetes, forming as a result of skin tissue breaking down and exposing the layers underneath. They are most common under the big toes and the balls of the feet, and they can affect the feet down to the bones. All people with Diabetes can develop foot ulcers and foot pain, but good foot care can help prevent them. One of the first signs of a foot ulcer is drainage from the foot that might stain the socks or leak out into the shoes. Unusual swelling, irritation, redness and disagreeable odour from one or both feet are also commonly early symptoms of a foot ulcer. The most visible sign of a serious foot ulcer is black tissue (called Eschar) surrounding the Ulcer. This forms because of an absence of healthy blood flow to the areas around the area around the Ulcer. Partial or complete gangrene, which refers to tissue death due to infections, can appear around the Ulcer. In this case, a malodorous discharge, pain, and numbness can occur.
