Can you tell me if diabetic foot ulcers ever heal?

Diabetic: Without an exam of the patient , vascular status , etc that is difficult to answer. Diabetic ulcers can take a long time to heal. See your podiatrist or wound care specialist for help

Yes they do: With proper care most can be healed.

Yes They definitely: Do, but require time and effort from you, the patient, to make it happen. You need to keep your diabetes in excellent control, perform excellent care of feet, keeping them clean, inspecting them at least twice a day, to ensure there are no cuts/abrasions, ; if you get them, they are immediately cleaned/protected to prevent them from getting infected. Complete courses of antibiotics as advised.

Yes.: With the right treatment they may heal.
