The primary functions of these sinuses are to warm, moisten and filter the air in the nasal cavity. They also play a role in our ability to vocalize certain sounds. Sinusitis, which is common in the winter, may last for months or years if inadequately treated. Symptoms may also include a plugged-up nose, a feeling of facial swelling, toothache, constant tiredness, and occasionally, a fever. Although colds are the most common cause of acute sinusitis, those with allergies may also be predisposed to develop sinusitis.
Allergies can trigger inflammation of the sinuses and nasal mucous linings.
This inflammation prevents the sinus cavities from clearing out bacteria, and increases your chances of developing secondary bacterial sinusitis. If you test positive for allergies, your physician can prescribe appropriate medications to control your symptoms, thereby reducing the risk of developing an infection. People with sinus problems and allergies should avoid environmental irritants such as tobacco smoke and strong chemical odors, which may increase symptoms. Surgery is sometimes needed to correct these problems. Many patients with recurring or chronic sinusitis have more than one factor that predisposes them to infection.
