Hello, According to your picture attached here Deviation of nasal septum we can't identify but your nose mucosa was very much congested. So nasal septum deviation alone is not a culprit, maybe i think u also have a sort of allergic mucosa. I do require a detailed history of any running nose / sneezing/ post nasal drip/ throat clearing/ throat ache/ recurrent throat infection etc. Another thing is to get your nasal endoscopy done in a nearby ENT clinic that will give you more ideas regarding your problem & also a solution for it.

There is mild deviation with turbinate hypertrophy. please get physical examination.

It looks mild deviation to left. Get physical check for proper assessment.
