A metallic taste is not generally severe and can be a sign of various things. Treatment will depend on the cause.
Why Do You Have Persistent Cough With Metallic Taste?
The fact that you do not see blood when you cough is assuring, because this makes it not likely that you have a serious infection or other source of bleeding in your chest or lungs. There are several conditions that can cause bleeding with cough, such as a tumor in the lungs or a tuberculosis infection; however, typically in these conditions the amount of blood that is produced suffices that it is apparent with coughing.
Nevertheless, it is still possible to ‘taste’ blood with cough associated to a number of other conditions. This metallic taste may be since of tiny amounts of blood from the irritation of the lining of the nose and throat from coughing or blowing your nose. It is also possible that the metallic blood taste is really from chronic mucus congestion, which often will produce a similar taste to blood.
