In brief: Either...or both

Not enough information to make a diagnosis but i suspect some friends and relatives are trying.
Here's a clue: allergic noses itch & sneeze while coughing is a sign of sinusitis. Watery runny nose? Think allergy. Thick goopy stuff? Sinusitis. Allergic rhinitis predisposes to sinusitis. Time to see your doctor?

In brief: Post nasal drip

Post nasal drip is a very common occurrence in both allergies and from infections.
Thus, the symptom of post nasal drip does not point towards one over the other.
