Ulcers should be treated by a doctor who can properly evaluate, diagnose, and treat any underlying medical conditions, as well as properly care for the wound to prevent infection.
Ulcers are persistent wounds or sores that do not heal properly or become chronic. Ulcers on the feet occur mainly due to reduced nerve sensation, poor circulation, vein dysfunction, and constant pressure to a particular spot. Diabetics are prone to foot ulcers. Ulcers may or may not cause pain and can be accompanied by swelling, discomfort, redness, itching, burning, and irritation.
