copper arthritis bracelet

How effective do you think copper jewelry in the treatment of arthritis?
Did you find what works for you? Do you wear rings, bracelets or what? How long have you used? Do any of other metals also a relief?
Well, I can say much about my father is 83 years for several years now and his joints ached so bad arthritis that was not funny. It started to wear a copper bracelet, and has been for years. He has not had any joint pain since. But I also think that depends on what type of arthritis that is how it works or not. And not in your head, either as in "if you think you are working and if not will." Saying that it is for the birds in this case. And it does turn your skin green, but guess what .. soap and water washing out, despite returning every day. But anyway, if not do more damage, which is a green skin.
