I have used magnets to eliminate stubborn pain. I think one was something torn in my shoulder. After a few months of chronic pain I strapped on a magnet from a set I had gotten as a gift. After wearing it daily, the pain vanished after maybe a week never to return. I had a similar stubborn pain in my wrist for a few months. Applied the magnet and after a week or so it too vanished and never returned. I don't know what it does or how but I'm a believer.
I had a buzzing sound in my ear off and on for the last six months. I purchased a magnetic bracelet on e-bay and noticed that it got less and then went away after about one week. The magnetic bracelets are a couple of dollars so not a big investment. I wear mine all the time even in the shower. They are actually a very attractive piece of jewelry. I am curious to know if anyone else has a similar response.
