About 20% of patients with mild PAD may be asymptomatic; other symptoms include:[1]

  • Claudication—pain, weakness, numbness, or cramping in muscles due to decreased blood flow

  • Sores, wounds, or ulcers that heal slowly or not at all
  • Noticeable change in color (blueness or paleness) or temperature (coolness) when compared to the other limb (termed unilateral dependent rubor; when both limbs are affected this is termed bilateral dependent rubor)
  • Diminished hair and nail growth on affected limb and digits
