Antibiotics are usually prescribed if you have yellow or green nasal discharge from one side of the nose, or both sides of the face
, localized pain on one side of the face
, or evidence of pus inside the nose. Doctors rarely take a sample of pus from your nose and actually test it, in order to determine if it is a bacterial or viral infection.
However, it’s a safe bet that a bacterial infection is present, because most of us already have bacterial in our upper respiratory tract.
