On August 10th, my daughter had to go to the ER for a kidney infection. She was in so much pain, I wanted to make sure what it was. She was put on antibiotics for a week, and I put her on probiotics as well for support. She ran the course of the meds and it was gone. Last week, she started having pain again, so I started her on frequency programs for anything I could find for kidney issues, stone, uti, etc. I also had her start on Colloidal Silver which I make myself. Within TWO days, the pain was gone and she feels fine, however, I am still running the programs for a few more days as well as the colloidal silver intake. I love this machine!!!
