Hi, I tried a magnetic mattress pad and magnets years ago and it did not do much for me when I used to get migraines, so I tossed them.(correcting dental work and detoxing and correct intake got rid of migraines) I also read some reports about magnets in healing, use only north pole side of magnet on body. I think it is best to remove cause of a problem, as MH teaches, by cleansing intestines and eliminating constipation from the body.
Hope this helps.
Good Luck.
