My problem is that I have patches on my feet. It's been a long time since I have ignored it and they do not seem to be subsiding. It is non-itchy and seems more like a dead skin at places but i am not sure. I tried using vinegar once (Just once) and pumice stone thereafter but to no avail. Please take a look at the images attached and provide me with your valuable suggestions. http://img820.imageshack.us/i/24082010108.jpg/
