Definition of Sinus Infection

Sinusitis, also recognized as a sinus infection or rhinosinusitis, is inflammation of the sinuses resulting in symptoms. General signs and symptoms comprise thick nasal mucous, a plugged nose, and pain in the face. Sinus infection is caused by infection from a pathogenic microorganism, which grows within a sinus and causes intermittent blockage of the sinus ostium.
