Mercury can be very dangerous. An MD trying to chelate mercury may well cause you much damage. The authority on mercury chelation is Andrew Hall Cutler, he is a PHD Chemist from Princeton, that had mercury toxicity and knew how to research mercury removal. see his website at http://www.noamalgams.com
Chelating mercury can be dangerous, Cutler is your best choice. I had mercury posion, lost several years of my life before I began to understand who to listen to. My priorities would be:(1) removal metal filings by a Biological, Mercury Free Dentist (2)clean colon (3) clean kidneys (4) flush liver (5) chelate mercury per Cutler's protocol.
