An arterial skin ulcer develops when poor blood flow prevents the skin and underlying tissues from receiving enough oxygen. These wounds often appear on the lower legs, tops of the feet, or toes, and are typically painful, especially at night or when the limb is elevated. The ulcer itself may look punched out with well-defined edges and a pale or dry wound bed. The surrounding skin can feel cool, look shiny, or show little hair growth due to reduced circulation. People with peripheral arterial disease, diabetes, or a history of smoking face a higher risk because their arteries are already compromised. These ulcers heal slowly without specialized care and may worsen if pressure or friction continues. Any persistent pain, discoloration, or open wound on the legs or feet should be evaluated promptly by a wound care specialist for an accurate diagnosis and treatment strategies.
Pressure Sores, Pressure Ulcers, and Arterial Ulcers Can Lead to Skin Breakdown
Not all wounds on the feet, ankles, and legs are the same. Pressure sores, pressure ulcers, and arterial ulcers may look similar at first, but develop for different reasons and require specialized care. Understanding these differences is key to proper treatment.
Pressure sores are often caused by friction at common rubbing points. Toes rubbing against each other can create small raw areas, while wearing ill-fitting shoes may lead to sores on the heel, ankle, or sides of the foot. These injuries usually begin at the surface but can quickly deepen if ignored.
Pressure ulcers, sometimes called bedsores, occur when the skin and tissue are compressed between bone and an external surface for long periods of time. On the lower extremities, they frequently appear on the heels, ankles, calves, or shins. Limited mobility, tight footwear, or prolonged bed rest can all contribute to these ulcers, which may progress through multiple stages from redness to open, infected wounds.
Arterial ulcers are different in that they result from poor circulation. When blood flow to the feet and legs is reduced, oxygen and nutrients cannot reach the tissue. Even small sores on the toes, heels, or shins may become painful, deep ulcers that heal very slowly. Unlike friction-related sores, arterial ulcers are directly tied to vascular health and often signal an underlying circulation problem.
All three types of wounds demand professional attention. A wound care specialist can determine the cause, relieve pressure, improve circulation when possible, and use advanced techniques to promote healing.
