Prior to amalgam removal I was noticing that I had on many mornings a very reddish triangle flairing down from my neck- sort of like a bandana. I would also have red blood blisters in the same area.
In the 2 years since total amalgam removal the condition is a lot less prevalent.
In fact when I do notice it coincides with what I call a bad mercury day. In my case, if I have the pink neck, if my ears are ringing and if my balance is a bit off then I know I will have a mercury dump day. So I take it cool and don't set up any stressful activities. I will say that these days occur a lot less than they used to. That is great news.
