legomyrego, are you there?
Please don't waste time. If you have ingested mercury, it goes first on your blood, from where it can be removed by chelation. But within days, it will pass to your bones and brains, where it stays indefinitely and makes you disabled.
So check if, where you live, a doctor is really necessary before making an analysis of mercury, gallium, indium, tin in your blood. This may save one day. If your doctor takes you in a week, go to an other more early. If the analysis finds Hg, have it removed quickly - I suppose in a hospital, as the procedure must resemble a dialysis.
