Use it, it wont do any harm. I personally cant wear magnetic stuff as it makes me feel sick but that does prove it does something. I used a 1000 human bracelet for Bo and it did seem to help, You don't have to put it where the problem is, anywhere on the body is meant to help as increasing circulation in one place will help it all over the body anyway. I also used comfrey which is meant to help healing of bones and soft tissue.
