It’s actually normal.
Your nostrils cycle between like this so that the one can take a break from the air flow and mitigate drying out.Not only does it help from drying out, but it helps with smell too; some things are better detected with a slower airflow
Yep, there’s a reason our noses didn’t simply evolve into a singular hole in the middle of our faces
Two nostrils allows for stereo smells. If we only had one nostril, we would only be able to smell in mono.
This is called the nasal cycle.
Use Flonase to help (need daily use for >= 4 weeks) If this doesn’t help enough, you should see an ENT.
Fun fact: the turbinates in the nose (which are responsible for the nasal cycle) have erectile tissue in them.

Also fun fact: don’t follow medical advice given by strangers on the Internet that claim they are an expert
You can never verify that claim
So, you are saying I should follow medical advice by strangers in the Internet?
Only if they don’t claim they’re an expert.
