to my knowledge there are no studies that demonstrate the benefits of copper for pain relief. the idea that copper can relieve pain has persisted since at least the 1970s. it seems to wax and wane in popularity. compression in itself may provide some pain relief because it offers support to joints ligaments etc. thus if a person experiences pain in a knee it's possible a compression garment would help alleviate some of this pain by providing support to the joint. another example is that of lower-leg pain caused by poor circulation. compression garments assist the veins in returning blood to the heart which may also reduce leg pain. however i personally feel a person should not use compression garments to treat pain or another medical problem except on the advice of a physician. using a compression device to reduce joint pain also might lead to a reduction in range-of-motion which can be bad in the long run. wishing you well!
is there any medical truth to copper-infused compression garments providing pain relief? . here is an example of a product: tommie copper
