What’s normal What’s not!
Nasal congestion is when your nose becomes stuffed up and inflamed. It can be uncomfortable and annoying, but it’s not usually a cause for concern. The most obvious cause of a blocked nose is a minor illness, such as a common cold or flu, and it’ll usually clear up after a week. If you experience congestion for longer than 10 days, or if it’s accompanied by a high fever or sinus pain, it could be a sign of something more serious.
