Sinusitis - What Happens

There are two types of sinusitis: acute (sudden onset) and chronic (long-term). Sinusitis often develops after a cold or viral infection.

Chronic sinusitis can lead to permanent changes in the mucous membranes that line the sinuses. As a result of these changes, you may become prone to having more sinus infections that may become more difficult to treat.
