5 Days Post-Op Rhinoplasty I have Inflamed Red Throat, is this Postnasal Drip?

I am 5 days PO for my rhinoplasty. The nose discomfort is almost nonexistent. But the sore throat is terrible. At first I thought it was the direct inflammation from traumatic suctioning of blood during surgery. The back of my throat looked like raw hamburger meat. But the throat now looks just slightly inflamed and not disfigured looking. I am starting to think this is now just a postnasal drip. Any ideas? If this is postnasal drip (surgical drainage), how long does this usually last.
