See subject. It’s usually a major, life-enhancing event when feeling miserable and muttering curses and drowning in snot from an allergy, not with a cold, where the feeling of misery is different.
It’s one of those full-force breathe-outs until the air tank is exhausted, a pause while holding the nose closed for a mouth-drawn refill, repeat process, do it for a third time so your Kleenex is now useless, and you think your brains might come out–but you so want to do it just one more time–and then you worry something might bust, and think of posting this thread, which you do with an IPad on your belly while lying backwards on the couch to let gravity drain your snot back into your brains.
I’ve heard of people rupturing sinuses by blowing up balloons through their noses. The Supreme Court isn’t the only folks poking around in uncharted waters.
Though there is something quite satisfying with that blow when the ears finally do that POP and you can HEAR again after living muffled for a week with plugged eustachian tubes…
Blowing hard can push the snot up into the sinuses, where the pressure of it sitting there will cause you pain, and it’s being packed in there and not being able to drain can lead to it festering.
Many years ago, my father ruptured a blood vessel in his nose by blowing too hard. Mom had to get him to the ER where it was packed; it was the only way to stop the bleeding.
I once lost my sense of smell after a lengthy cold with considerable nose blowing. It lasted for 2-3 months IIRC. Bad enough that I went to the doctor and had a Cat-scan or MRI or some such thing. They didn’t find anything and eventually it came back.
