For years I was using various medical magnets to help reduce pain and promote healing.
The 'basis' behind these magnets are to increase the blood flow to the area where the magnets are placed. So that allow sounds good.
I had all sorts of medical magnets. Round ones, large squares, credit card size, etc.
I did get some temporary relief using this type of alternative treatment. Overall, I think they are good for
acute problems (ie Sprains, Muscle pulls, etc) but I dont know how much the help in the long run.
