I began using Tommie Copper compression products for my osteoarthritis. I have developed rashes everywhere and it is painful. Is it possible I have too much copper? I was using the compression garments on my knees and hands. As soon as the first rash developed I quit wearing them. After I quit wearing them the rash began to spread to other parts of my body (arms, waste, ankles). Other symptoms that I have experienced are headaches, nausea, a metalic taste, burning and itching. What should I do?
