Still coughing?: There are several possibilities. The most likely is that you have mucus dripping from your sinuses down your throat and collecting at your vocal chords. This will lead to a wheezing cough and a sensation of congestion in your upper chest. The treatment is nasal saline, nasal steroids, and anti-histamines. If it is not this, there remain nearly a dozen other possibilities.
