Hi, My Mom is was hospitalized and is now in a rehab center. She has had venous insufficiency and a cold painful right leg for 3 years.The bottom portion, from the knee down, on both legs are blue and the skin is painful to touch and she is constantly getting tears on her thin skin. Can she use crème chelation therapy to enhance bloodflow to the lower legs? What else can I give her to improve the periphertal artery disease? She is 93 years old and 4 weeks age she was doing everything for herself except cooking. Now she is so weak she can t even turn herself in bed because they wouldn t take her out of bed for two weeks in the hospital. (she went into the hospital for bladder infection) The legs are now my biggest concern.Thanks,Janet
