I have a Metallic Taste in my mouth, PLEASE HELP???!?

Are you taking any medicine or vitamins? A lot of meds can cause a metallic taste in the mouth for a while. That's a main cause for that taste. Of course, so can blood, but you'd probably know if your mouth was bleeding unless you have an oozing sore in your mouth. Don't know, but maybe a loose filling can cause it too. Doesn't seem likely though. Medicine is the most likely cause.
