What Are The Signs And Symptoms Of Peripheral Artery Disease?

Signs of peripheral vascular disease: (quick and dirty answer)
Pulselessness:  Pulses are not detectable in the part of the body distant from the heart (in the foot or the hand)
Paralysis (self-explanatory)
Paresthesia: Alterations in sensation in the limbs
Pain (see claudication, below)
Pallor:  Loss of color to that limb; sometimes it worsens with the raising of the limb when the patient is lying on his/her back.

The usual signs of PVD (complicated answer)

• Intermittent claudication
  (cramping):  Symptoms are precipitated by walking a predictable
  distance and are relieved by rest.  Sometimes it presents as the hip or
  leg "giving out" after a certain period of exertion.  This does not
  occur with sitting or standing, just with exertion.
• Ischemic rest pain is worse, since it is due to a combination of
  PVD and inadequate perfusion / circulation to the extremity.  It is
  often partially or fully relieved by placing the extremity in a
  dependent position, so that perfusion is enhanced by the effects of
  gravity.
• Leriche syndrome is a clinical syndrome described by intermittent
  claudication, impotence, and significantly decreased or absent femoral
  pulses. This syndrome indicates chronic peripheral arterial insufficiency due to narrowing of the distal aorta.

Ideally to get more information about any potential risk you may want to consider health screening and talking to your primary health physician. I recently found out that there is preventive peripheral artery disease screening available.
