Symptoms of nonallergic sinusitis lasting anywhere from a few hours to a few days may include:
- Severe runny or stuffy nose
- Clear or slightly colored mucus
- Post nasal drip with a persistent cough
- Facial pain, swelling and pressure
- Altered sense of smell
In some cases, no relief may be found or symptoms worsen with the use of over-the-counter medications.
Causes and Risk Factors
People who are sensitive to dust, smog, smoke, strong odors and chemicals may experience nonallergic sinusitis. Temperature changes, along with changes in humidity and stress may also be triggers.
Other causes may include:
Infections - Viral infections, such as a cold or flu, may trigger nonallergic sinusitis. Though the attack may last a short time, patients often experience ongoing post-nasal drip, discolored mucus, facial pressure and pain.
Hormones - Pregnancy, menstruation, menopause, hypothyroidism and oral contraceptive use may trigger a nonallergic sinusitis reaction.
Diet - Alcoholic beverages and hot, spicy foods may result in a nonallergic sinusitis attack.
Drugs - Anti-inflammatory drugs such as aspirin and ibuprofen, beta-blockers, sedatives, antidepressants, erectile dysfunction drugs and, in many cases, overuse of decongestant nasal sprays, may bring on nonallergic sinusitis
