Not: Believe I might have answered this question before. Your problem is more likely an allergic one than an infection. If the mucosal edema is >6 mm, the probability of a sinus infection is higher. Treat the allergy and the problem will likely improve.

Sinus: CT findings only. No indications for antibiotics given rest of your history.
