<human>: hello. I keep getting a strong metallic taste in my mouth, especially behind one tooth, and the tip of my tongue tingles as it would if I had burned it on coffee, but I havent had anything hot. I have not had a change in diet and I am not taking any new medicines. I quit smoking two weeks ago. Any ides on what this might be?
<bot>: Helllo thanks for consulting at Chat Doctor.usually metallic taste and tingling sensation results from various vitamin deficiencies.like iron, it B12 ETC, so please consult a general physician for a complete blood check up and treatment,,,If YOU are middle-aged, with stress factor-- it might also be because of burning mouth syn Chat Doctor. .so maybe you are having relapse episode???either ways please consult an oral physician and general physician for a check-up and treatment,hope it helps,take care,
