Q. A 36-year-old female presents to the clinic to establish care. She complains of a nasal congestion and an occasional cough. She described that the cough is dry and nature and states that it has been almost a year that she has been experiencing these symptoms. When asked about the frequency and triggers, the patient answers “it comes and goes and I have not been able to identify any particular triggers.” There are no associated eye or ear symptoms. There is no history of rash, wheeze or pruritis. Past medical and family history are unremarkable. On examination, the patient is vitally stable. Oropharyngeal examination reveals an erythematous and boggy mucosa. Chest examination is clear of wheezing, rales, and crackles. What is the most likely diagnosis?
