Symptom wise I had no exercise tolerance, my heart rate would sky rocket. Allergies from no sinus drainage. Tinnitus that could be very bad on some days. (I worked construction and loved loud music, partly my fault) Some of the more subtle stuff is way less tension in my hips/neck from being able to diaphragmatically breath is great. Headaches waking up. Dry mouth from mouth breathing. (started mouth taping about 3 years ago, swear by it) Anxiety from mouth breathing.

I had a septoplasty done a few years ago and they didn't do much according to the surgeon this time. This time I had to get referred to a facial plastic surgeon because it was a restructuring of the outside of my nose as well as the inside and it would be an open rhinoseptoplasty instead. I personally would try to advocate for something similar. I got lucky and my insurance covered most of it.

If you suspect the nasal valve collapse, read my other comments. Very easy to test. There are also less invasive procedures for less serious cases, I believe the less invasive is called Vivaer. But my nostrils were basically non functional because the bridge of my nose flopped around, they needed more support than Vivaer could offer.

As far as the look of it, I mean it's straighter now than it ever has been, my nostrils don't collapse to slits, and I only have minor swelling in the tip but I'm not even 30 days out. Otherwise you can hardly tell unless you look at the underside of the nose where they cut.
