Leg and foot wounds that are slow to heal; unexplained leg pain or cramping, especially during exercise or walking; and skin problems or discoloration on your legs and feet, poor nail growth are some of the symptoms of Peripheral Arterial Disease.

Dr. Bernie Fernandez, Chief Executive Officer of Baptist Health Medical Group, says if you have a wound or an ulcer in the foot that is taking a long time to heal, you wonder if it could be from repeated trauma or decreasing of circulation, which helps to aid in the healing of the wounds. He also points out you can have no symptoms and still suffering from PAD.
