I have been using the Theralumen for several months on a daily basis for general health purposes. While I have seen improvements in my general energy and health, I noticed something I didn’t expect. I have had very dark blotches on my feet for years. They were not painful but I have had loss of feeling in my feet and I always thought that whatever caused one problem caused the other. Recently feeling began to return to my feet and the dark patches are disappearing. I have to tell you that I am so encouraged by this response. Something good must be happening. Nothing else I have tried over the years I have had this problem has worked.
