Sinus Infection |
|
|
One of the most common reasons for sinus infections is allergies. In fact, most acute sinus infections follow symptoms of runny nose caused by allergy, colds or other viral upper respiratory tract infections. Our sinuses drain into the nasal cavity through a narrow area called the ostia, which are just 1 to 3 mm in diameter. The ostia can be obstructed through the combination of thick mucous and inflammation and swelling of the lining of the sinus cavities. To make matters worse, the small hairs of the cavities, which generally sweep away secretions, are impaired. All of this can make it easier for bacteria to grow and cause the infection. Symptoms of a sinus infection include facial pain or pressure, green or yellow nasal discharge, headache, ear pain or pressure, and may even include fever. Steam, decongestants, and ibuprofen can help relieve some of the blockage and pain. Nasal decongestants should be used for no longer then 3 to 4 days, or symptoms may worsen. Before taking any medicine, make sure you read the label and adhere to any precautions. If the symptoms are severe or have continued longer than a week, see your doctor. A doctor will most likely prescribe antibiotics because it can be difficult to tell the difference between a viral or bacterial infection, and if the symptoms have been there for more than a week, there’s an increased risk of bacterial infection. You may also be prescribed a nasal steroid, which can also help reduce inflammation and may be useful for people with chronic allergies or frequent infections. |

What about using antihistamines? Antihistamines may dry the nasal and sinus secretions, making it difficult to clear the mucous. However, they may be useful in people with allergies, to reduce the allergic symptoms. | |
