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. Most sinus infections improve on their own, but sometimes they develop into a bacterial infection—swelling, inflammation, and mucus production caused by the cold can lead to blockage in the nasal passages, which may encourage the growth of bacteria.
Acute sinusitis, whether viral or bacterial, may develop into chronic infections that may last 3 to 8 weeks or longer. 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.
Complications of sinusitis (such as an infection of the facial bones called osteomyelitis) are relatively rare. However, when complications occur, they may be life-threatening and often require extensive medical or surgical treatment.
