If you are having trouble breathing, you keep sneezing, and your head feels like it might explode, you may very well be congested. In other words, fluid may have built up in your sinuses and your lungs.

Being congested is a typical but very unpleasant symptom of the common cold. This adjective literally means “clogged,” “overcrowded,” or “overfull.” Congested is also used to describe arteries that are clogged, cities that are overpopulated, and roads that are full of traffic.
