I have a deviated septum, but the doctors in the US doesn't think its medically necessary to do Septoplasty and I also have a sleep apnea, come to think I should get this done.
For comparison, I used some of those nasal strips before surgery and the post-surgery were very comparable, so that might be an inexpensive option to try? I also recall someone mentioning some sort of nose plug thing from Amazon you could get that does the same thing.
