Take a look at your feet and lower legs from time to time.
PAD can cause skin-color changes. The affected foot or leg may become unusually pale, discolored, bluish, or red depending on its position and the severity of impaired circulation.
Color

A small cut on your foot should gradually heal.
When blood flow becomes severely impaired, tissues may not receive enough oxygen and nutrients for normal healing.
