10 Signs of the Flu

Flu Sign #3: Congested Nose
Mucus is common in the body and helps to perform various useful functions. As mentioned above, it is very good at catching pathogens which can then be expelled from the body. The nose naturally uses a particular type of mucus, which we commonly know as snot. When we have the flu, this mucus can build up in excess, causing congestion.
Excess mucus is only part of the reason for the congestion, though. In addition, the soft linings of our nostrils can become inflamed and swollen, further restricting the passageway. A congested nose can be quite uncomfortable but it is not necessarily something that you need to be concerned about.
