Luckily I've healed since the operation but still have mild symptoms a few months after. For a while, I had too much "openness" in my nose which felt like there was little to no air resistance. I still get that sometimes. I'm lucky though because I'm back to 70% normal. However, I'm in a private Facebook group for ENS sufferers with over 3,000 people and reading about their daily struggles is absolutely brutal, especially since I was going crazy after experiencing them for only a week or two.
For anyone considering a turbinate reduction, DO NOT DO IT. The risks are too great, and unfortunately the ENT community has a perverse incentive to hide the facts. To give you a sense of this, the week after my operation when I was struggling with the suffocating feeling, I told my ENT surgeon and he coldly offered to give me antidepressants. I was shocked and livid, because I knew that he knew exactly what was going on, but instead of acknowledging the problem, he tried to sweep it under the rug and treat it as a psychological illness. I guarantee you as someone who's experienced it, it is everything except for psychological.
You won't find good data on ENS risk because almost no ENTs will actually diagnose it. My primary ENT (not the ENT surgeon who performed the operation) basically told me that I didn't have it because I still had my turbinates. This is also blatantly false [0]. My ENT suggested that I should see a pulmonologist but my lungs are totally fine. They will do everything they can to deny and deflect responsibility. Don't let yourself been their next victim.
Feel free to reach out to me if you have more questions or are considering getting a turbinate reduction. My contact info is in my profile. I cannot urge you strongly enough to avoid this operation at all costs.
