I’ve realised nasal spray is more of an illusion of having an unblocked nose but the pressure is still there, but what actually goes on to clear the nose?

The active ingredient in the spray I think you’re talking about is Oxymetazoline, which causes blood vessels to constrict. This has a huge effect on reducing mucous production, and *some* effect on reducing swelling. For minor, transient cases this can really unblock someone, but past a certain level of inflammation you’ll get the “Illusion of having an unblocked nose,” as you put it. There’s also a lot of downsides, you can experience rebound congestion, and habitual use can lead to long-term rebound upon discontinuation.
