My mother has a number of foot blisters/sores that are not open or weeping, but painful nonetheless. Unfortunately, she has peripheral arterial disease and is a smoker, but she had stents put in her legs more than one year ago, so the circulation to her feet should be improved. We see the doctor regularly for follow-up and ultrasound to be sure that the blood vessels in her legs are open and allowing good blood flow, but we don't seem to get good advice on how to handle these foot sores. Does anyone have experience and advice that can help me? I'd like to know if there is any medication that I can put on the sores that will relieve her pain. I'm currently using only moleskin patches. Thanks in advance, everyone!
