Venous statis ulcers, neurotrophic ulcers and arterial ulcers are common types of foot sores, according to Cleveland Clinic. Dry skin and swollen feet accompanied by an itching or burning sensation are common symptoms.
Venous statis ulcers form below the knee, just above the ankle and can affect both legs. Patients with varicose veins, leg swelling and frequent blood clots in the leg are prone to these sores. The ulcer is characterized by swollen skin and is reddish in color with occasional yellow or green discharge, notes Cleveland Clinic.
Neurotrophic ulcers are common in diabetic patients and can affect anyone with poor foot sensation. The sores can develop anywhere on the feet but usually occur at the increased pressure points under the feet. The lesions can range from pink to red or brown to black in color. They tend to tingle or go numb and sometimes cause pain. The surrounding skin is often hard and calloused, according to Cleveland Clinic.
Arterial ulcers or ischemic ulcers can form between the toes, on the heels or on the tips of the toes. Recently removed ingrown toenails and repeated forceful toe nail trimmings increase the risk of ischemic sores. The wound is often yellow, grey, brown or black in color. It is typically extremely painful at night and requires the patient to appropriately angle the leg for pain relief, states Cleveland Clinic.
