Nasal congestion makes the nose feel blocked so that breathing becomes difficult. It is often caused by the inside of the nose becoming inflamed or irritated, which makes the nose produce more mucus.
Nasal congestion can be caused by a variety of conditions, such as:
- Nasal polyps
- Septum deviation.
Various medical and surgical options are available to manage nasal congestion. Speak to your GP or consultant if you are concerned.
