Hello, I believe that Miracle-Mineral-Supplement is a cancer killer. I have seen several pre skin cancers drop from MDH one on his neck, one on his leg and one on his arm, and three drop away from my face and several from my ankle and finger. I would call Jim Humble if you have any questions. You can contact me by Email on this post there is a link to my email. Hope this will work for you. Your husbands soreness may be the action of the Miracle-Mineral-Supplement on his Cancer. Be well, MW
