What is a symptom commonly associated with sinusitis?

Fever is a common symptom associated with sinusitis because it often accompanies infections, which can occur in the sinuses. Sinusitis is the inflammation of the sinus cavities and can be caused by viral, bacterial, or, in some cases, fungal infections. When the body fights off an infection, it frequently results in an increase in body temperature, leading to fever. This physiological response helps the body combat the pathogens causing the infection.

Other symptoms of sinusitis may include nasal congestion, facial pain or pressure, and thick nasal discharge, but fever is a key indication that the body is responding to an infectious process.
