Stiff Neck with Metallic Taste tied to the neck/shoulder tension.

I thought it was muscular from my kitchen Job, but after three+ weeks and the Metallic Taste I am wondering if the Four 30 year+ Amalgam Fillings should come out. I know of one Dentist in my VT. state that does it with attention to Mercury vapor etc. Anyone have any ideas like a story reference that might make some sense out of this one. I recently had a fixed top retainer put in after a retainer tooth adjustment and may be grinding my teeth at night releasing Mercury? IT is strange I can almost feel how the taste is connnected though to the neck/shoulder spot on the left side. I do have three out of the four fillings on that side? Tweet
