Rhinitis, also called allergic rhinitis, is the term used to describe the condition that occurs when your body reacts to allergens. In other words, when someone says their allergies are bothering them, they could also say they are currently suffering from rhinitis. Sinusitis, also referred to as a sinus infection, occurs when the lining of your sinuses becomes inflamed due to an infection caused by either a virus, bacteria, or (rarely) a fungus. You can also get a sinus infection if your sinuses are regularly blocked by congestion, for example, or by a nasal obstruction, such as a polyp.
