What is Sinusitis?
Sinusitis is an inflammation of the sinus lining caused by bacterial, viral and/or microbial infections; as well as structural issues like blockages of the sinus opening. If the sinus opening is closed, normal mucus drainage may not occur, which may lead to infection and inflammation of the sinuses.
What are the different types of sinusitis?
There are two main categories of sinusitis: acute and chronic. Sinusitis is usually preceded by a cold, allergy attack or irritation from environmental pollutants. Often, the resulting symptoms, such as nasal pressure, nasal congestion, a "runny nose," and fever, run their course in a few days. However, if symptoms persist, a bacterial infection or acute sinusitis may develop. If sinusitis occurs frequently or lasts three months or longer, it may be chronic sinusitis.

- Facial pain, pressure
