I strongly suspect my chest pains, dizziness, pressures on the sides of my head, and occasional aggression and forgetfullness are linked to the fillings in my teeth, but how can I be tested for mercury poisoning? I've felt so rotten, for so lon, and have run back and forth to doctors i.e., neurologists, urologists,..and nothing appears wrong from their perspective. Yet, I am absolutely suffering at times, frequently tired, and more frustrated as to not know what is causing all of this. I also get pressures o the end of my fingers on occasion. My appetite is generally OK.
