A few years ago a guard where I work had his wife develop lung cancer. The cancer was very advanced when I learned of it. She had severe back pains that medications would not ease very much. I told the man about castor oil packs and actually gave him the things needed to administer the packs. He told me the next day that the packs were the only thing that gave her a lot of relief from the pain.
I mention this because I know you are familiar with Edgar Cayce and the castor oil packs. Hopefully your wife will not be in pain enough to warrant the use of packs.
You and your wife are definitely both in my prayers..........
