Shortness of breath, particularly during activity.
-

-
Cold feet or legs, especially when one side feels noticeably colder.
-
Numbness or weakness in a leg or foot.
-
Slow-healing cuts or sores on the feet or legs.

Skin color changes in a foot or leg, such as unusual pallor, bluish coloration, or redness.
-
Weak or difficult-to-feel pulses in the feet.
