What?

Boogers. It’s when you realize you can smell boogers.

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

Metallic and milky 🤮

If it smells like decomposing calcium, you have tooth decay and should see a dentist. Most sneezes don't smell.

Tonsil stones?

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

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

Blood and brain.

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.

How often do you brush your teeth? Maybe the sneeze is drawing in mouth-air?

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

This is so fascinating because yeah, a sneeze isn't supposed to smell, this is entirely unrelatable to me.

Get that checked out.

Only time I have a post sneeze smell is when I have a nosebleed about to start.

Citrus

Smells like antibiotics

Because I'm currently taking antibiotics

it's like degaussing your cranium.

All-dressed.

gasoline, but less colorful

It's the smell of daemons leaving your body.

God bless you.
