I get severe headaches, post nasal drip, foul smell associated with sinusites. The ct scan revealed bilateral concha bullosa, paradoxical right middle turbinate narrowing the osteomeatal unit and cranial part of the nasal airway. Minimal deviation of the nasal septum, mild to moderate hypertrophy of the turbinates at the posterior part of the nasal airway. The doctor suggests surgery, please advise.
