I have no idea why it works for me, it doesn't work for my daughter and her fibromyalgia at all. But I KNOW one thing, I no longer wake up in the night with my toes curled BACK in positions I couldn't even get them into during my waking hours. My big toe sticking straight out sideways, to the INSIDE of my foot. The intense pain, so bad that if there was a gun in the end table, I'd have used it on myself, anything to get out of that misery night after night. I have been psychoanalyzed, sanitized and I think maybe even pasteurized, but nothing about those magnets has put me in the hospital, which is more than I can say for Tegretol and Mysoline. So I'll keep right on using my magnets, taking my four Sinemets per day and keep right on truckin!! P.S. I don't sell magnets, nor do I know anyone who does. just me, Marjorie
