Need expert help here. what are the symptoms of foot ulcers?

You may not: Have any symptoms. Some people with ulcers are neuropathic or don't feel anything......An ulcer is a hole...If you have one see a doctor..

Ulcer: As said there are no real symptoms , but you may have poor circulation , insensate feet etc that will predispose you to ulcer formation. An ulcer is a hole in the skin sometimes very deep and very easily infected. See your podiatrist asap if you have one !

Have it evaluated.: All diabetics could develop a foot ulcer. Patients with diabetes are particularly susceptible to foot ulcers primarily because of neuropathy, vascular insufficiency, and due to a diminished healing ability. Patients with diabetes lose the protective sensations for temperature and pain. Impairing awareness of trauma such as abrasions, friction, and blistering, can lead to ulceration.
