You can never have too many magnets, they work wonders. I am living proof. I went from not being to walk far and having terrible lower back and knee pain, taking medicine all the time and barely making it out of bed to feeling better and better everyday! I wear a bracelet on my left arm and an anklet on my right ankle to help with the pain and improve balance. I am a true believer!! It does work! I hardly ever take them off, even when I sleep.
