My foot is doing great. Three days before vacation things were looking grim. The rash all around it was pink and swollen and had blisters throughout. Popi suggested trying to soak it in epsom salts. Fortunately I had the capacity to do that at home that night. For three days in a row I soaked it and by the third day all the pink color was gone and the blisters were gone and I was healing. Now I still have lots of skin layers that haven't evened up, but there is no more raw skin. I may finally be healing. The sand can irritate it, but it's not really painful.
Thanks for asking.
