Many people have had this problem including myself. It is a very tricky topic. There isn't really a clear answer to the question of whether correcting the deviated septum will fix your symptoms. There are people with ENS that have had septum surgery that have had symptoms improve and some that have had the symptoms get even worse.  If you are too open on the side that the septum is deviated away from and possibly still get true obstruction on the side the septum is deviated towards, then correcting the septum could improve your symptoms. But since you are changing the aerodynamics of the airflow, it is not certain what impact the surgery will have. In my case, I have been told that correcting my deviation is something to consider but should be considered cautiously as it is uncertain what the results will be. If you have a turbinate (or two) that has been severely damaged or reduced, the main issue could be the turbinate itself and correcting the septum may not help the problem and it is another surgery. At the moment, I am concentrating on healing the turbinates and avoiding any additional surgery until I believe that is my only/best option.
