I have been thinking about my situation. i first got a reaction from amalgam days after the first placement in '75? I was put on antibiotics...another placement in '84 prompted an mri when I experienced vision abnormalities and arm paralysis, leg dragging. The mri showed 1 lesion. so dx possible ms. Had flares directly after each (2) subsequent amalgam placement over 25yrs. last mri in 2008 was frightening. Brain full of inflamation and 'holes'. Maybe it is too late for chelation?
