Changes in a foot or lower leg can be as important as pain. NHLBI lists PAD symptoms that can include one foot feeling colder than the other, pale, discolored, or blue color changes, leg weakness or numbness, pins-and-needles feelings, slow-healing sores, and reduced toenail or leg-hair growth NHLBI. The American Heart Association also notes slow-healing wounds on the feet or toes, cooler temperature in one foot or lower leg, slow-growing toenails, little or no hair
