21 year old male,i have nasal valve collapse, when i breathe in, one nostril caves in substantially, and the other caves in slightly this issue started 2 years ago when i had/still have sinusitis, one year ago i had a septoplsty/ turbinate reduction and this might have mad this issue worse.my nose gets substantially less congested once i eat very clean(been doing this for about a week now) so if surgery didnt initially cause it, and the completely blocked nasal passages didnt, then what did?
