Unusual skin coloring
One of the things doctors look for is a change in the color of your legs. When raised, a leg may be white because of compromised blood flow.
Then, when the leg is dangled from the table, it can turn reddish or purplish in color, says Dr. Schneider, because the body has dilated the blood vessels to increase flow to the feet.
In some people with PAD, the feet or toes are pale or bluish when they’re sitting, due to a lack of circulation.
