That kink is a polyp inside your nasal area mate - my GP stated a painful operation & it will grow back eventually here have this nasal spray - it has worked fine for the last 15 years ....I’ve got a kink in one of my nasal passages Joey, so have difficulty breathing through my nose. I was offered an op a good few years ago to sort it and declined due to the hell you go through afterwards.
I’ll see what the doc says
