Thanks I just read some reviews on how STRONG these are and how some used for OA and other pain issues. I'd like to try the Applied Mag on my knee but not sure how to use them....just placing them on knee etc. Many reports on people buying them to hold shower curtains....not my issue. Pain control would be what I would look at. Thanks again.

Just reading more, could be I should not use these since I have metal in my thigh with hip replacement.
