Ischemic foot refers to a lack of adequate arterial blood flow from the heart to the foot. There are a wide variety of possible causes, including arterial blockage from cholesterol deposits, arterial blood clots, arterial spasms, or arterial injury. With ischemic foot, the person suffers from an inadequate blood supply reaching the foot to provide the oxygen and nutrient needs required for the cells to continue to function and/or heal.
Symptoms typically include cold feet, discoloration in the toes, muscle cramping, pain in bed at night that is releived by getting out of bed and walking, ischemic ulcers.
Treatment includes walking exercises to increase blood flow, wearing protective shoes, and medications. Note: Please consult with your physician before taking any medication.
