Sinusitis

Sinusitis is a common inflammation of the paranasal sinuses, which produce the mucus required for nasal passageways to function normally. It can be acute or chronic, and can be caused by fungus, viruses, bacteria, allergies, or an autoimmune reaction. The many types are as follows: Chronic sinusitis: After 12 weeks, symptoms typically return. Subacute sinusitis: Symptoms last four to twelve weeks longer than the typical acute phase. The most common type of sinusitis is acute, which can last up to four weeks. It is also possible that more substantial treatment, such as surgery, will be necessary.
