Who Knows Noses?

I have a question: does a healing wound smell? And I don't mean an infected wound.

Okay, now I'll explain. See, it started a while ago: when I picked up a can of Coke Light to drink, for a split second, I would smell something bad. Like, just for a whiff, one of those whiffs that you can't seem to smell again afterwards, no matter how you try. And if I picked it up again immediately after to drink again, I would smell nothing. I thought for a while that maybe my breath was an issue, but it isn't.

So I tried experimenting and all this, and here's what I found: if I breathe with my nose, I smell nothing out of the ordinary. I can sniff little or sniff with big intakes -- nothing. But if I stretch my face downwards (kind of like before people rub their noses, how they make their faces long), I smell it.

And it's not pleasant.
It smells, ... well, it stinks.
It smells like poo.

And yet, if I just keep my face normally, I get only normal smells. Weird, huh?? Perhaps normally, the air doesn't really rush by that area in my nostril, and only does when I stretch my face down. Oh, also happens if I press the tip of my nose down, like flatten it down. Can you imagine that?

And the only thing I can think of is that I once had a gash in my right nostril, but that was years ago (and no, I don't know how it happened). Maybe that wound reopened (though it doesn't hurt) and I'm smelling the healing process ... which begs the question I had before, whether healing wounds smell funny.

But a later shocking discovery: the smell comes through my left nostril, but not the right! And it must be just in the front inch or so, because a change in my nose shape changes the symptoms, and that's all that I can imagine being affected by my facial expression.

So ... I'm kind of ... well, concerned.

I mean, nothing is bleeding and nothing is swelling up, and it doesn't seem to be a life-threatening situation. But it's annoying and concerning.

The only time I don't get it is immediately after a shower, and when I've just woken up in the morning. I wonder if it's some kind of combination of pollution outside or the hotter weather giving my nostril sweat?

Wait, do our nostrils even sweat?

Dammit, this is really perplexing! I might have to see the doctor about his. Help!
