I did a septoplasty surgery in May 2018 with slight turbinate reduction. Months passed by with little to no noticeable improvement. On Jan 23rd 2019, I did another surgery for strengthening the nostril cartilage, preventing nasal collapse and another slight turbinate reduction. My breathing improved for a few days and then it went back to being congested. There seem to be some sort of inflammation causing this but I don't know what is causing the inflammation. Smoke? Dust? Diet? What should I do now?
