Peripheral artery disease is the narrowing of arteries that bring blood to your limbs, particularly those in your legs. When the arteries narrow so much that blood flow is reduced or cut off altogether, this can cause leg pain when walking and numbness, mild to severe tingling, cold feet, and poor wound healing. Here, Dr. David Greene R3 Stem Cell tells you about peripheral artery disease and how to treat it with stem cell therapy.
