My wife is privy to different medical periodicals, essays and such. According to some of the stuff I have read "magnetism" does have a positive place in health care, with regards to aches and pains. What some of these authors are not sure of, and/or don't agree on is how magnetism works. Is it actually a physical type of relief, or is it psychological? The best "pain" thing that ever happen to me after I was injured in a golf cart accident was a KOA foam mattress. I had a lower back pain that no one could do anything with. It was not a big problem, just sometimes annoying. Did not bother me golfing. Anyway, after a couple of nights on this foam mattress, my back issue was gone...completely. I asked the management what type of mattress they were using, and they told me it was a cheap version of those space age foam memory mattresses. I asked, but they would not sell me one of their new, unused, stored mattresses. Once home we purchased one those memory foam mattresses. Best sleep, body aid we ever purchased.
