Now he has a fever and his cheek hurts . There are several possible causes of your husband's problem, but a runny nose, fever, and headache are common symptoms of sinusitis. Sinusitis is inflammation of the sinuses around the nose. Problems of the nasal airway include allergies, upper respiratory viral infections, and true infections of the sinuses. You are right to be concerned about your husband, because fever is not a common symptom of nasal allergies.
Fever can signal inflammation or infection.
The sinuses are air-filled cavities within the facial bones and the skull which normally drain a small amount of mucus into the nose. When this lining becomes inflamed, the sinus does not drain effectively, leading to a build-up of mucus or even pus within the sinus. Nasal inflammation caused by a cold, allergies, tobacco smoke, or air pollution can block effective sinus drainage. The sinus openings may be narrowed or obstructed. Genetic disorders such as cystic fibrosis can also prevent proper sinus drainage, leading to chronic infection.
