I have a deviated septum filling my right nostril 90% ish and externally leans to the left quite marked. In the last year ive started noticing my smell is hindered and testing it my left nostril even though clearer isnt as good as my right. My ENT specalist tells me i have a curved C septum, could this cause my loss of smell on that side. He believes it could be viral but im worried it might be first signs of Alzheimer's as per the peanut test of left/right impairment. Im considering septoplasty
