A small blister or sore on the foot is easy to brush off. For a person with diabetes, though, even a minor wound deserves a closer look. Diabetes can affect the nerves in the feet and may also reduce blood flow. That means a cut can go unnoticed and may take longer than usual to heal.
So, what does a diabetic foot ulcer look like? There is no single appearance. It may begin as a red patch, a cracked area, a blister, or a small open sore. Some ulcers stay shallow at first. Others become deeper if they are not treated early.

What Is a Diabetic Foot Ulcer?
A diabetic foot ulcer is a wound occurring on the foot of a person with diabetes. It commonly occurs in areas that experience a lot of strain, like the heel, ball of the foot, or toes.
One reason these wounds can be missed is reduced feeling in the feet. A person may step on something, develop a blister, or get a small cut without noticing it. If blood flow is also poor, the skin may heal more slowly.
What Does a Diabetic Foot Ulcer Look Like at First?
Early signs are sometimes quite mild. The skin may still be closed, or there may only be a tiny break in it. You might notice:
- A red, brown, or darker patch
- A blister or small crack
- Dry or peeling skin
- A callus around one spot
- Slight swelling or warmth
- Fluid on the sock
- A sore that does not seem to heal
Pain is not always a useful warning sign. Some people with diabetes have less feeling in their feet, so an ulcer may be present even when it does not hurt.
How Can a Diabetic Foot Ulcer Change?
If the wound gets worse, the skin can open more and the sore may become deeper. The area may look round or uneven. There may also be yellow or white material inside the wound.
Other changes can include redness around the sore, swelling, drainage, a bad smell, or dark tissue. In more serious cases, the wound can reach deeper layers below the skin.
Signs the Wound May Be Infected
An infected ulcer needs medical care quickly. Watch for redness that spreads, increasing warmth, swelling, pus, or a strong smell. Fever or chills can also be a warning sign. Dark or black tissue around the wound should never be ignored.
It is also worth remembering that a serious ulcer may not be very painful. If the foot looks different, feels warmer than usual, or has a wound that is not healing, it is better to have it checked.
Where Do Diabetic Foot Ulcers Usually Show Up?
These ulcers often appear in spots that deal with regular pressure or rubbing. The heel and ball of the foot are common areas. They can also develop on the toes, between the toes, or along the sides of the foot where shoes rub.
A quick daily foot check can make a real difference. Look at the top and bottom of each foot, around the heels, and between the toes. If you have trouble seeing the bottom of your feet, use a mirror or ask someone you trust to help.
A diabetic foot wound is something that cannot be overlooked despite its size. The wound care team at Magnet Health NY in the Bronx treats diabetic foot ulcers and other wounds, which heal gradually. The personnel can examine the wound, observe the tissue and circulation around it, and develop a treatment plan that will meet the needs of the patient.
Final Thoughts
Knowing the appearance of a diabetic foot ulcer helps to identify trouble at the first signs. It can start off as a small blister, skin crack, or a callus, or an area that appears dissimilar to the adjacent skin. It can potentially develop into an open, swollen, or draining wound later.
For people with diabetes, small foot changes matter. Checking the feet regularly and getting timely care for wounds can help prevent a minor problem from becoming much more serious.
