Hair loss on the legs is another common sign, as adequate blood flow is necessary for hair follicles to thrive. The description of a small circular wound accompanied by intense pain while walking is also indicative of arterial ulcers, as they often present as well-defined, pale wounds that are painful due to the lack of oxygen-rich blood.
