Things You'll Need:
- Thermometer
- Doctor
- Nasopharyngoscope
- X-ray
- Computed tomography
-
Step 1
Check for thick nasal discharge. This discharge will resemble snot, except that it's thicker and might have a greenish color. Discharge is often heavier in the mornings.
-
Step 2
Take your temperature regularly. Use a thermometer to ensure that your body's temperature stays near 98.6 degrees F. A rapidly rising fever is one of the first signs that you may have developed a sinus infection.
-
Step 3
Inspect your eyes. It's common for people suffering from a sinus infection to exhibit signs such as swollen eyes and tear ducts. Check to see whether the skin around your eyes has become inflamed.
-
Step 4
Check for any tenderness or pain in your face. Gently press on your cheekbones and the area surrounding your nose to test for a reaction. Use facial pain as a means to diagnose any swelling or inflammation that might be occurring within your sinus cavities.
-
Step 5
Discuss the symptoms you've observed with a doctor. By evaluating your symptoms and your medical history, a doctor will be able to diagnose a sinus infection officially. Expect to have your ears, nose and throat examined.
-
Step 6
Have a nasopharyngoscope inserted into your sinuses to inspect for signs of swelling or infection. A nasopharyngoscope is a slim tube containing lights and a tiny digital camera that can be inserted into your sinuses by way of your nostrils. The images it captures can be used to determine causes of sinus pain.
-
Step 7
Get an x-ray of your face to inspect for signs of inflammation. The images obtained in an x-ray can provide clear proof that you're suffering from a sinus infection. Before you're able to get an x-ray, though, you'll first need a doctor's orders.
-
Step 8
Apply for a computed tomography to be made of your head. Like an x-ray or a nasopharyngoscope, a computed tomography image can be used to diagnose a sinus infection. This can be an especially effective way to evaluate sinus conditions deep within your head.
