I have been suffering anxiety for a while and had three panic attacks this year. Anyway about 2 months ago i woke up with high pitched tinnitus in my right ear like a dog whistle sound but it went away last month and I was free of the tinnitus. Anyway just this week I went to the dentist and got a white filling put in my front tooth. When I got home I did oil pulling by swishing coconut oil around my mouth and I got a metallic taste in my mouth that I don't usually get with coconut oil. Anyway I never thought anything more of it until I was tidying up my house when all of a sudden I got a clogged sensation in my left ear and I can now hear a ringing sound in the same left ear where I got the pressure/clogged feeling. The pressure/clogged feeling has disappeared but I'm still getting the ringing in that ear and it's been three hours now. My question is could the metallic taste be the mercury from the white filling and is it the reason for the clogged feeling and tinnitus?
