@sueinmn you described all the symptoms that my wife had! It took 11 years and 6 hip surgeries to get her Cobalt / Chroumin levels down to a “ normal” level. It all started with a Stryker implant and ended with same implant only with ceramic coating. One revision she had zero symptoms but blood work indicated elevated levels of Cobalt / Chroumin and then two added staph infection. Brain fog and hair loss were / are very visually presently. There is / was a class action lawsuit against Stryker for their failed implants; that does nothing for the person experiencing these symptoms and who know the long term implications from these elevated levels? One Needs To Be A Strong Self Advocate! If You sense an issue do not stop until you get an answer
