At the end of the day my shoulders are painfully sore. I have tried a heating pad and hot baths, and then a was offered the loan of a mattress and pillow with magnets. I was sketical about their effectiveness, and surprised at how they helped me. The magnets promote circulation and generate heat and each morning after sleeping on this mattress I am refreshed and ready to begin another day. Has anyone else experimented with magnets? I did some research and there are a number of medical studies that have shown their effectiveness in treating varioius injuries and pain in general. Rose
