In his explanation of fungus, Jim Humble says the clay will not be activated without petroleum jelly. He describes the sensations I feel and describes how applying Miracle-Mineral-Supplement and DMSO makes the skin more painful and sore the more you apply it, when fungus is present, as happens to me. The question just this day in my mind is, I think there are likely more scenarios than that. A newer topic than mine mentions a need for taurine. So, I am convinced Miracle-Mineral-Supplement has the answer for me. Just need to figure out the skin.
