What Is a Sinus Infection?

5. Irritated Nose Lining
There are numerous potential causes of a sinus infection, and one of them is that the tissues lining the inside of your nose become irritated and inflamed. One of the most common reasons for this is the common cold, so some people that catch a cold will go on to develop sinusitis.
Another potential cause of this irritation is rhinitis. This basically means that the lining of the nose is easily irritated. Rhinitis can be both allergic and nonallergic, but it is usually allergic rhinitis, particularly from hay fever, that results in a sinus infection. If you have allergic rhinitis then antihistamines should be able to relieve you of your symptoms.
