question: i HAVE BEEN DIAGNOISED WITH A SINUS INFECTION...BUT I HAVE THE MOST AWFUL TASTE , SMELL ODOR WHEN I BREATH BLOW MY NOSE.  iT IS LIKE SOMEONE DIED IN MY MOUTH.  I HAVE HAD STREP BEFORE I AM NEGATIVE now never had anything close to this.  I am on an antibiotic.  It can't be just from sinus.  My teeth are in good shape.
