Arterial Wounds: Warning Signs, Causes and When to Seek Care

Arterial wounds can occur when poor blood flow prevents the skin and underlying tissue from receiving enough oxygen and nutrients to heal. They often affect the toes, feet, heels, ankles or lower legs. Even a minor cut may become serious when circulation is reduced. Common causes include peripheral artery disease, diabetes, smoking, high blood pressure and high cholesterol. Warning signs may include severe pain, a cool foot, pale or shiny skin, reduced hair growth, weak pulses, and a deep “punched-out” wound that is slow to heal. Not every persistent wound has the same cause. Venous ulcers, diabetic foot ulcers and pressure injuries need different treatment. A healthcare professional should assess any wound that is worsening, painful, foul-smelling, draining unusually, or showing signs of infection. Early medical attention can help identify circulation problems and prevent complications. People living with diabetes or known circulation issues should check their feet and lower legs regularly and take small injuries seriously.
