• Drainage from your foot, which can stain your socks or leak out in your shoe, is one of the first symptoms of a foot ulcer. Early signs include unusual swelling, irritation, redness, and odours in one or both feet.
• The black tissue (called eschar) that surrounds a severe foot ulcer is the most visible symptom. This happens when there isn’t enough healthy blood flow to the region around the ulcer.
• Around the ulcer, partial or full gangrene, which refers to tissue death caused by infections, may develop. There may be odorous discharge, discomfort, and numbness in this case.
• Foot ulcers do not always show symptoms. Ulcers can often go unnoticed before they become infected.
• If you notice any skin discoloration, especially blackened tissue, or if you experience pain around an area that appears calloused or irritated, consult your doctor.

The Wagner Ulcer Classification System will most likely be used by your doctor to determine the severity of your ulcer on a scale of 0 to 5: 0: there are no open lesions; the lesion may have healed.

1. A shallow ulcer that does not reach deeper layers

2 A more serious ulcer that extends to a tendon, bone, or joint capsule

3. Abscess, osteomyelitis, or tendonitis affect deeper tissues.

4. Gangrene in a forefoot or heel section

5. A gangrenous infection that affects the entire foot
