What else besides GERD can cause mucous in my nose and throat?

Brian J. Broker, MD
Ear, Nose & Throat (Otolaryngology)
Mucous is naturally present in the throat. The sensation of "post nasal drip" or mucous in the throat occurs when the mucous is thicker than normal or when reflux (GERD) causes swelling at the base of the throat. Mucous is most often made thicker due to allergies. Other causes are dehydration, or dryness of secretions, due to aging, illness or medications. 

Contrary to allergy medication advertising that suggests you "dry up" your post nasal drip, you actually want to make your secretions more moist to relieve the sensation.
