I've had burning, tingling, stabbing pains for some time now. Of course merury is a potent neurotoxin.

My mother has just been diagnosed with Trigeminal Neuralgia, a condition that involves excruciating pain in the facial area. Some people have linked it to mercury poisoning. My mother had many amalgam fillings at one time but they have all been replaced with composite fillings. Of course the mercury that she absorbed from them could still be in her body.
