You either have tonsil stones or a chronic sinus issues. Talk to an actual doctor.

Edit: But in answer to your question … the smell is bacteria that your sneeze has stirred up.
Tonsil stones are basically piles of bacteria. Chronic sinus infections are more bacteria. Those are the two most likely sources.

I don’t smell anything after I sneeze… You should probably check with a doctor to make sure you don’t have an infection.

Blood and brain.

I always wonder if things always smell this way and the sneeze just removed what was covering it up from my nose.

It’s the smell of daemons leaving your body.

God bless you.

Tonsil stones?

I only get it when I’m sick or about to be. Usually a sign of a sinus infection. Seems like mucus that hasn’t fully engulfed the source of infection still carries enough out to have a smell.

You guys have a smell after you sneeze? I just feel pain throughout my body after them sometimes.

I can’t describe it, but I know EXACTLY what you mean.
