No worries, what you have is part and parcel of an airway inflammatory syndrome which apparently affects your lower airway (wheeze) your central airway (cough) and your upper airway (sinus changes on the CT). The ENT guy will only operate if there is obstruction of the osteomeatal complex or if there is a fluid collection that will not drain of if there are polyps, and you have none of these things. Antihistamine, decongestant, flonase, saline irrigation, plus or minus singulair and advair, then most of all you need to find what is causing this airway inflammation, maybe allergy but seldom in adults, more likely an occupational or other exposure to something toxic. Look hard at all the other medications you take (ACE inhibitor, SSRI). Something is causing this, right? FInd it.
