Sinus infections occur in all age groups. The mucus membranes that line the sinuses sometimes become inflamed and infected. When this happens, the sinuses do not drain properly. They may be full of mucus, which facilitates the growth of harmful bacteria. Other causes include nasal polyps, allergies, tumors or viral or fungal infections, according to the Centers for Disease Control (CDC). Sinus infections may linger and become more problematic with time. There are many symptoms to a sinus infection, including respiratory and body-wide symptoms.
Nasal Infection
A stuffy nose and fluids being released from the nose may be signs of a sinus infection. Nasal congestion may increase as the sinus infection lingers.
Painful Throat
A painful throat is often a sign of a sinus infection, according to MedlinePlus. It may be due to postnasal release of mucus from the sinuses.
Exhaustion
Exhaustion may be a symptom of a sinus infection. This condition may sap energy and leave a patient feeling too fatigued to carry out normal tasks.
Headache
A headache may be a sign of a sinus infection, notes the CDC. As the nasal and facial area becomes swollen because of the nasal infection, headache pain occurs and may become intense. The headache may occur sporadically or may be ongoing.
Limited Ability to Smell
An inability to smell often develops with a sinus infection, notes MedlinePlus. As nasal passages become clogged with mucus, the sense of smell disappears either partially or completely.
Unpleasant Breath
Breath that has an unpleasant odor may be a symptom of a sinus infection. Without proper airflow in the sinuses, mucus and debris may accumulate and become stagnant. This may lead to a foul smell from the breath.
Cough
A cough that becomes more severe in the evening hours or during sleep may also be a sign of a sinus infection. A sinus infection may impede sleep because of a problematic cough.
Fever
An elevated temperature may be a sign of a sinus infection. As the infection advances, the fever may become a more serious problem.
