My daughter had been online trying to find me (mom) something to help my back pain. Don't like taking pills pain pills...She came across Real Time Pain Relief website, ordered some for me, fell in love with it after the first try. It really helped me and we try to keep some on hand at all times. Now I use it on my knees...It really does work for me. I have even let my coworker use it for her lower back, and she said that it helped her. Real Time Pain Relief works wonder for my back.......
