Having different taste in mouth for past few days. taste like blood.

LayOffThGarlic&Onion: That bloody taste is also sometimes called a"metallic" taste-maybe 'cause blood contains iron(and hopefully not lead).But there are many causes of this,from poor dental hygiene to certain food reactions,medications and certain illnesses(like in the liver or intestines). Often it just comes & goes (unless you're a vampire which,in that case,would be an occupational hazard). See a doc if it persists
