What diseases or disorders can the nose have?
One disored that your nose may have is a deviated septum- this is where the bone that splits your nostrils is skew; either because it grew that way or you broke your nose. This can create a blockage in your nose, making it difficult to breath.
Another disored is small nostrils; this also makes it difficult to breathe and can be a cause of snoring. It is also a sign of cancer so see you docter straight away before its to late.
