I've been wearing a copper bracelet for 37 years since I had a pain in my shoulder. Now I wear two - one on each wrist.It was my BIL who told me about them. They have worked for me. I've had arthritis in my lower back for many years but it is rare that I'm aware of it.
I now have rheumatism and the last time I saw the specialist he noticed the bracelets but made no comment so I assumed that he wasn't actually opposed to them.
I can see no reason why you should not wear one or two. They don't cost much and are better than taking medication.
