(Sinus Infection)
Sinusitis is an infection of the sinuses, which are the hollow cavities within the cheekbones, around the eyes, and behind the nose. It is typically caused by a bacterial infection that may develop following a respiratory infection. When mucus gets blocked from draining properly out of these cavities it becomes a site for bacterial growth. Individuals with allergic rhinitis or asthma are more likely to suffer from sinusitis because of the chronic inflammation experienced in these conditions often obstructs the flow of mucus. Similarly, individuals with structural abnormalities, such as a deviated nasal septum, are more susceptible to sinus infections as well
