How can i resolve the issue to shrink my right nasal turbinate so i won't get any infections. like what should i do i have flonase spray ?

Turbinate reduction: It sounds like you have had a number of infections and someone says you have a large turbinate. Nasal steroid sprays can help decrease swollen turbinates a little, so feel free to try using this daily for a month. But if you really have turbinate hypertrophy, it may well not shrink enough to change how often you are infected. If not, you might need a surgical reduction. See an otolaryngologist/ENT
