I have my own bad experience.. I got glasses and all body rash that itched until I was bleeding. it happened within few weeks after placing Amalgams in my teeth.
my rash cleared, but still have skin problems.
4 months ago, some of my rash returned to my elbow and so my pimples.. also got few times fatigue and fevers. same time my tooth with the Amalgam got cracked, i didn't realize, just thought it seemed deeper than usual but didn't pay attention to it. then that tooth broke. i see it so obviously it because of this not a mere concidence.
