DMSO also helps with the pain. I also use a mortar & pistle to grind up a bunch of zinc tablets into a fine powder and then dip my finger in DMSO and then into the zinc powder and rub it into my lower back and then the outbreak. It seems to be pretty effective. Be very careful though with DMSO as it goes right through the skin and takes anything with it (detergent from your clothes) right into the cell. Also, it will cause your cells to retain and absorb water so you probably only want to do it every other day or once a day if in major pain.
