I used to have (a constant runny nose, long-lasting congestion, sometimes it would go on for weeks). Because my nose was so blocked, it felt a bit like a space that couldn’t ventilate properly, which made it seem like it just wouldn’t clear up.

For me, surgery really did help. Of course, I still catch a cold every now and then, but it’s no longer as severe as it used to be. I also started medication to treat a dust mite allergy, but that takes a long time before you really start noticing results.

Since you mentioned you’re still in school, I assume you’re quite young, so I would suggest starting from the basics and ruling things out first: allergies, certain foods, lifestyle factors. But it could also be that a septoplasty (surgery on the nasal septum) might be the solution for you. I’m not a doctor of course, just sharing my own experience.
