In brief: Infection or not
Sinus infection is when an organism colonizes the linings of your sinuses and lives there causing symptoms including pain and secretions.
Congestion occurs as a reaction of the sinus lining to a variety of agents and irritants and fills up with secretions. It can lead to infection, but responds to irrigation and decongestants. They can occur simultaneously.
