Could You Have Sinusitis?


Sinusitis affects four pairs of sinuses called the paranasal air sinuses, which connect to the nasal passages. Sinusitis is an infection in these sinuses. An infection can be caused by allergies, certain medications, changes in the air or abnormalities in the sinuses themselves. Acute sinusitis is the most common form of this condition.

Self-Treat? Or See a Doctor?


For example, you could treat a head cold by taking a $6 over-the-counter (OTC) medication for congestion and cough. The bill just for walking in the door of your doctor’s office could be $50 to $80 or more. Even if you only have to pay $10 to $20 in co-pay for an office visit, using an OTC medication still saves you -- not only money, but also time.

When Your Child Has Sinusitis

Sinuses are hollow spaces in the bones of the face. Healthy sinuses constantly produce and drain mucus, which helps keep the nasal passages clean. But an underlying problem can prevent sinuses from draining properly. This can lead to sinusitis (sinus inflammation and infection). Sinusitis can be acute or chronic. Acute sinusitis comes on suddenly, often after a cold or flu. When acute sinusitis doesn’t go away or comes back often, it’s said to be chronic. Long-lasting sinusitis is usually due to allergies or a physical blockage in the nose.

Why the Doctor Looks in Your Nose

Have you ever wondered why your health care provider will look inside your nose during an examination? When a patient has a runny nose or congestion, the health care provider needs a good look at the source of the problem.

Providers usually don't look inside your nose unless they have a specific reason. Usually, they are looking for an infection or allergy. Sometimes, they're looking for other sources of your breathing problem, such as a deviated septum which is a shifting of the wall that divides the nasal cavity into halves.
