Common symptoms is an understatment. You have what we have. Mercury poisoning. My ears have not shut up in years. I have been to an ENT as well and he says my ears are fine. He has no idea what could be causing this unless I was exposed to heavy metals somehow, which he didn' t think I had because none of my previous employment involved metals or factory work. (he didn't make the connection).
I have the funny lights when I close my eyes. The strange dreams/nightmares. The think you have been sleeping for six hours in only two. The thyroid that is shot.
In a word, yes, it is familiar. At least you got the filling out. Now you can begin to detoxify the metals.
