Why do sneezes go away?

Answer 1

You mean when you need to sneeze but it suddenly goes away at the last moment?

It's frustrating and maddening, and it happens to all of us.

Some tips:

When you feel a sneeze coming on, close your mouth, flare your nostrils, and inhale slightly and sharply through your nose. This may help you to complete the sneeze as it will strengthen the sneeze impulse sent through your nervous system and make it less likely to fritter out and leave you in frustration with your nose burning way inside, sometimes even your sinuses as well! (I have so been there!)

If you're troubled by a lot of sinus and sneezing troubles, you may suffer from year-round or seasonal allergies. Millions of people do; there's no shame in it! If the trouble is very severe, you may need to make an appointment to see an Allergist. Although panels can be run to test for common household and outdoor allergens, not everything can be covered. But your allergist will know what to do from there if it gets to that point.

More likely, you're only occasionally troubled by sneezes - incomplete or otherwise - and if you follow some of the basic procedures to control allergens such as dust mites around your home, you should be okay.
