leftover orthadontic glue

This may sound like a silly question at face value, but I am dead serious... I am 30 years old and I have what feels like leftover glue from the braces/retainers I had some 15+ years ago.   I have had unexplained neurological symptoms, mainly a chronic headache and vertigo despite a $30,000 workup at a major hospital.    Is there some chance this leftover glue, or possibly even the mercury in my fillings could cause these symptoms?   I have about 7 silver colored fillings and one I believe was grinded down by the dentist years ago after it was filled to make my bite better.    Any thoughts are appreciated., thanks.

I do not think either one of these is the cause of your problems. There is a group of professionals that do believe mercury is toxic to your system but I am not a component of that theory.
