What is diabetic ulcers on the feet look like?

Deep and Moist: Diabetic ulcers are usually deep and moist. Usually located at pressure points on the bottom of the foot. If infected they will drain smelly fluid. These are very serious and you should see a physician.

Many Possibilities: A diabetic ulcer occurs when there is loss of sensation below the ankles (neuropathy). This allows your feet to become injured without you knowing. There is really no specific appearance but rather, they simply occur as cracks in the skin, cracks in callus that result in skin tears below, and other wounds in that area resulting from loss of tissue. Healing occurs when you stay off the injured area.

Have it evaluated.: A diabetic foot ulcer is best diagnosed with a physical exam. Your physician will ask you to remove your shoes in order to inspect your feet. They will look for redness, calluses, bruising, blistering, swelling, and for open sores. Sometimes the ulcer may be hidden and will be discovered following the debridement of calluses or the deroofing of blisters.
